I don't undestand how to solve this problem

Answer:
Volume = 20
Step-by-step explanation:
To find volume of the shape you split the shape into two shapes: A triangle or pyramid and a rectangle
The volujme of a rectangle is W x L x H
A = 2 x 5 x 8
A = 80
The volume of a pyramid is
A = [tex]\frac{1}{2}[/tex]Bh The B is the area of the base so B = L x W = 5 x 2 = 10 so B = 10
A = [tex]\frac{1}{2}[/tex] 10 x 4
A = [tex]\frac{1}{2}[/tex] 40
A = 20
