Find the volume and surface area of a rectangular box 4 ft by 2.9 ft by 3 ft.

1 answer

The volume of a rectangular box is given by the formula:

Volume = length × width × height

For the given box, the length is 4 ft, the width is 2.9 ft, and the height is 3 ft.

Therefore, the volume is:

Volume = 4 ft × 2.9 ft × 3 ft = 34.8 ft³

The surface area of a rectangular box is given by the formula:

Surface Area = 2(length × width + length × height + width × height)

For the given box, the length is 4 ft, the width is 2.9 ft, and the height is 3 ft.

Therefore, the surface area is:

Surface Area = 2(4 ft × 2.9 ft + 4 ft × 3 ft + 2.9 ft × 3 ft) = 88.6 ft²
