Question

Find the volume of the pyramid with a square base where the perimeter of the base is 8. 7cm and height of the pyramid is 6. 3cm round your answer to the nearest tenth of the cubic centimeter

Answer 1

9.9
`cm^(3)`

Explanation:

Formula:

1/3(area of the base x height)

1/3 [2.175(2.175)(6.3)]

1/3(4.730625)(6.3)

1/3(29.8029375)

9.9343125

Is the perimeter of the base is 8.7, we need to divide that by 4 (2.175) to find out the side length of the square. The area of the square, we need to multiply 2.175 by 2.175.

9.9343125 rounded to the nearest tenth is 9.9
