Question

Find the volume of the figure. Round your answer to the nearest tenth if necessary

Answer 1

Answer:

The volume of the figure is $8\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a triangular pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the base

H is the height of the pyramid

Find the area of the triangular base B

$B=\frac{1}{2}(3)(4)=6\ ft^{2}$

we have

$H=4\ ft$

substitute the values

$V=\frac{1}{3}(6)(4)=8\ ft^{3}$
