Question

Find the height of each pyramid.

Answer 1

Answer:

a) height =14in

b) height =27cm

Step-by-step explanation:

Greetings !

a)

$v = \frac{l \times w \times h}{3}$

where,

• v=448in³
• w=12in
• l=8in

Substitute these values and solve for h.

$h = 3 \frac{v}{lw} \\ h = 3. \frac{448}{8.12} = 14$

b)

$v = \frac{1}{3} ah$

where, a=area of the base

• h= height

plug in the given values and solve for h

$v = \frac{1}{3} ah \\ 3v = ah \\ h = \frac{3v}{a} \\ h = \frac{3(270)}{30} \\ h = 27cm$
