A pyramid has 5 sides including the base. If the base is a rectangle L long and W wide, its area is L*W.

The other sides are triangles. If the height of the pyramid is H, the triangles that are L wide at the base will have a height of the square root of half of W squared plus H squared, or SQRT((.5*W)^2+H^2) and the two that are W wide at the base will have a height of SQRT((.5*L)^2+H^2). The area of a triangle is .5*height*base, so the total surface two triangles with the same height and base is 2*.5*height*base = height*base.

So, the total surface area of a pyramid L long by W wide by H tall would be:
L*W (the area of the base)
+ L*SQRT((.5*W)^2+H^2) (the area of the 2 triangles with base L)
+ W*SQRT((.5*L)^2+H^2) (the area of the 2 triangles with base W)

Hope this is helpful!

Assuming the base of the pyramid is square ... of length B and the distance from the center of the base of the pyramid to the top of the pyramid is H

Surface area is: 2 x H x B
plus B-square (if you include the base of the pyramid)

False I reckon. The vertices are the angles

It is already in decimal for. Maybe you mean fraction?
0.705=705/1000=(141*5)/(200*5)
After simplification by 5 you get 141/200

Since the 'base' and 'top' of any prism have the same shape, the surface area can be found by
  • surface area of prism = 2 * area of base + perimeter of base * H
So for the rectangular prism in your example..
  • surface area = 2LW + 2(L+W)H
  • = 2 * 7 * 4 + 2*(7+4)*5
  • = 56 + 2 * 11 * 5
  • = 56 +110
  • = 166 sq cm
Hope this helps

Surface area of any prism is the sum of the areas of the sides
A trapezium is A = h(a + b)/2
h is the perpendicular height, a and b are the parallel sides
