Question

If the smaller pyramid has a surface area of 25.49 ft2, what is the surface area of the larger pyramid? Round to the nearest hundredth.

height 6 small pyramid
height 15 large pyramid

Answer 1

`A = 159.31\,ft^(2)`

Explanation:

Let consider that both pyramid are simmilar. The surface area of the pyramid is directly proportional to the square of the height is:

`A = (25.49\,ft^(2))\cdot \left((15\,ft)/(6\,ft) \right)^(2)`

`A = 159.31\,ft^(2)`
