The base of a straight triangular prism is a right-angled triangle with legs 9 and 12 cm. Its height is 10 cm, determine the volume of the prism.

To answer this question, we must figure out that the volume of the prism is equal to the base area * height, and the base area is a triangle, where 2 legs from a right triangle are already known, therefore the base area is (1 leg * 2 legs) / 2 = (9 * 12) / 2 = 54, and the volume of the prism itself is 54 * 10 = 540.
