Question

Can someone help me with the volumes of pyramids please for a brainless and points​

Answer 1

Explanation:

Volume of a pyramid = (l×b×h)/3

V = 128cm^3,

l = 8cm

b = 8cm (/because is a square base)

Substituting this values

128 = (8×8×h)/3

Cross multiply

128×3 = 64h

384 = 64h

Dividing through by 64

h = 384/64

h = 6cm

Height is 6cm
