Question

If the volume of a square-based pyramid is 300 cm cubed with a height of 9 cm, then what is the height of the base?

Answer 1

9.4868 cm Rounded: 9.5cm

Explanation:

V(Volume) = 1/3 x B(Base area) x h

300 = 1/3 x B x 9

10 x 1/3 = 10,3

300/10,3 = 90

B = 90^2

l(length of the base) =
`\sqrt 90` = 9.4868

Rounded Answer (to the first decimal) = 9.5
