Question

Find the height of each pyramid.

Answer 1

a) height =14in

b) height =27cm

Explanation:

Greetings !

a)

`v = (l * w * h)/(3)`

where,

• v=448in³
• w=12in
• l=8in

Substitute these values and solve for h.

`h = 3 (v)/(lw) \\ h = 3. (448)/(8.12) = 14`

b)

`v = (1)/(3) ah`

where, a=area of the base

• h= height

plug in the given values and solve for h

`v = (1)/(3) ah \\ 3v = ah \\ h = (3v)/(a) \\ h = (3(270))/(30) \\ h = 27cm`
