Question

in japan, farmers have created watermelons in the shape of rectangular prisms. find the volume of a prism-shaped watermelon in cubic inches if its length is 10 inches, its width is 2/3 foot, and its height is 9 inches

Answer 1

Given:
rectangular prism.
length = 10 inches
width = 2/3 foot
height = 9 inches

convert width from foot to inches. 1 foot = 12 inches
2/3 foot * 12inches/ft = 2/3 * 12 inches = 2*12/3 = 24/3 = 8 inches

Volume of rectangular prism = length * width * height
V = 10 inches * 8 inches * 9 inches
V = 720 in³
