Question

What is the height of the triangular prism below if the volume equals 1,638 cubic millimeters?

Answer 1

Volume of the prism is the area of the triangle x the height.

To find the height find the area of the triAngle first, then divide the volume by the area.

Area = 1/2x 7x18 = 63 square mm

X = 1638/63

X = 26 mm
