Question

Find the volume of a pyramid with a square base, where the perimeter of the base is

Answer 1

Answer:

40.3 cubic foot

Step-by-step explanation:

Perimeter of the pyramid's base=11.1 ft

Now, this is a square base, and we know that:

Perimeter of a Square=4l

Therefore: 4l=11.1

l=11.1/4=2.775 ft

• The length of a side of the base =2.775 ft
• Height of the Pyramid =15.7 ft

Volume of a pyramid

$=\dfrac{1}{3} X Base Area X Height \\=\dfrac{1}{3} X 2.775^2 X 15.7\\=40.3 ft^3 (correct to the nearest tenth of a cubic foot.)$
