The volume of the prism is 2400in³
The volume of a prism is generally expressed as;
volume = bh
where b is the base area and h is the height of the prism.
The base of the prism is trapezoid. The area will be area of trapezoid.
Area of trapezoid = 1/2(a+b)h
where a and b are the two non parallel sides.
A = 1/2( 8+12)10
A = 1/2 × 20 × 10
A = 100unit²
Height of the prism = 24in
Therefore , the volume of the prism is
V = 100 × 24
V = 2400 in³
