Find the volume and surface area of a rectangular box 5 ft by 2.5 ft by 4 ft.
The volume of a rectangular box is calculated by multiplying its length, width, and height. In this case, the volume is given by:
Volume = 5 ft * 2.5 ft * 4 ft = 50 ft³
The surface area of a rectangular box is calculated by finding the area of each side and summing them up. A rectangular box has 6 sides. In this case, the surface area is given by:
Surface Area = 2 * (5 ft * 2.5 ft) + 2 * (5 ft * 4 ft) + 2 * (2.5 ft * 4 ft)
= 2 * 12.5 ft² + 2 * 20 ft² + 2 * 10 ft²
= 25 ft² + 40 ft² + 20 ft²
= 85 ft²
