Question

Find the volume of a right prism with height h=10 cm, if: b The base is a trapezoid with height htr = 3 cm and bases of 2 cm and 5cm

Answer 1

You will use the formula V = Bh, where B is the area of the base of the prism.

In this case use the formula for area of a trapezoid.  A = 1/2 h (b1 + b2)

V = Bh
V = 1/2 x 3 x (2 + 5) x 10
V = 105 cubic cm

The volume of the prism is 105 cubic centimeters.
