What is the volume of a pyramid 4 cm,4 cm by 12 cm

Alenkinab [10]

Answer:

The volume of pyramid with dimensions 4cm , 4cm by 12cm is $\bold{64 \mathrm{cm}^{3}}$

Solution:

Volume of a pyramid can be found out by using the below formula,

$\bold{v = \frac{1}{3} l w h}$

where,

v is the volume of pyramid

l is the length of pyramid

w is the width of pyramid

h is the height of pyramid

from question, given that l = 4 ; w = 4; h = 12

hence the volume of pyramid for the given dimensions is

$v = \frac{1}{3} \times 4 \times 4 \times 12$

$= 4 \times 4 \times 4$

$= 64 \mathrm{cm}^{3}$

So the volume of pyramid is $\bold{64 \mathrm{cm}^{3}}$
