Answer:
56 cu in
Step-by-step explanation:
Here we are asked to find the volume of a right rectangular pyramid. The formula for the same is given as
[tex]V = \frac{1}{3}lbh[/tex]
Where given that
l = 4 , w = 6 , h = 7
[tex]V = \frac{1}{3} \times 4 \times 6 \times 7 [/tex]
[tex]V = 4 \times 2 \times 7 [/tex]
V=56[/tex]
The volume of the right rectangular pyramid is 56 cu in
