### Rectangular prism is made from centimeter cubes. What are the dimensions of the prism width x length x height? What is the surface area of the prism? What is the volume of the prism?

Dimension of the prism is the number of cubes in width x length x height.

Surface area is 2(w x l) + 2(l x h) + 2 (wxh)

Volume is the number of cubes.

Good luck,

Paul

### How many gallons in an 88" x 15" x 9" trough?

try this :

Instructions
1. Measure the rectangle length, width and height. For example, 8 inches long, 6 inches wide, 10 inches high.
2. Multiply the length by the height, then double the product. With this example, 8 inches multiplied by 10 inches results in 80 square inches, which multiplied by 2 equals 160 square inches.
3. Multiply the width by the length, then double the product. With this example, 6 inches multiplied by 8 inches equals 48 square inches, which multiplied by 2 equals 96 square inches.
4. Multiply the height by the width, then double the product. With this example, 10 inches multiplied by 6 inches results in 60 square inches, which multiplied by 2 equals 120 square inches.
5. Sum the amounts from Steps 1 through 3 to find the rectangle surface area. So adding 160, 96 and 120 square inches results in 376 square inches.

### How to calculate cubic feet ?

Calculating the cubic feet of a space requires multiplying the area of the bottom times the average height. You get the bottom area by multiplying the length times the width. Remember, to get cubic feet, you need all your measurements in feet to start with.

VOLUME (in cubic feet) = Length (in feet) X Width (in feet) X Height (in feet)

If it's a rectangular room you're working with, it is all straightforward. If there are irregular walls, it may be necessary to divide up the room into rectangular sections and then add together their individual volumes. If the ceiling is sloped, you need to use the height that has the same ceiling area above it as below it. Good luck! Truly.

### Volume of rectangle formula

A rectangle is a two-dimensional figure and doesn't have a volume. It has an area equal to length times width. A rectangular prism has a volume equal to length times width times height.

### The volume of a rectangular prism is 2,058 cubic cm. The length of the prism is 3 times the width. The height is twice the width. Find the length of the prism

Right Rectangular prism, Length L, width W, Height H
Volume=2058 cm^3=L*W*H
However
L=3W, and H=2W
(3W)*W*(2W)=6 W^3=2058
W^3=(2058/6)=343
W=Cube root of 343=(343)^(1/3)=7 cm
L=3*7=21 cm
H=2*7=14 cm

### A toolbox is 2ft. high and its width is 3ft. less than its lenght. if its volume is 80ft.

We find volume by using V = H*W*L , where H = height , W = width, and L = length. You say H = 2 ft,
V = 80 ft ^3, and W = L - 3 . Put all of these back onto the equation and we will have
80 = 2 * (L - 3) * L . We can condense this to be 80 = (2*L - 2*3 ) * L then becomes 80 = 2*L*L - 2*3*L
simplifying this we get 40 = L*L - 3*L . This is also 40 = L * (L - 3) this is a quadratic equation, meaning that
we will get two answers for L. In this case L = 0 and L = 3. Since 0 ft would mean that the tool box doesn't
have a length we will use L = 3. We can now put this back into our original equation to find out what the
width is. 80 = 2 * W * 3, this is 80/6 = W = 13.3333 . Now we know that W = 13.3333 and L = 3.
