Find the volume and surface area of a rectangular box.
6.4in 5in 3in
To find the volume of a rectangular box, you multiply its length, width, and height. In this case, the length is 6.4 in, the width is 5 in, and the height is 3 in.
Volume = length x width x height
Volume = 6.4 in x 5 in x 3 in
Volume = 96 in³
The volume of the rectangular box is 96 cubic inches.
To find the surface area of a rectangular box, you need to find the area of each side and then add them up. For a rectangular box, there are six sides: the top, bottom, front, back, left, and right sides.
Top and bottom surface area = length x width
Front and back surface area = width x height
Left and right surface area = length x height
Surface area = 2(length x width) + 2(width x height) + 2(length x height)
Surface area = 2(6.4 in x 5 in) + 2(5 in x 3 in) + 2(6.4 in x 3 in)
Surface area = 12.8 in² + 30 in² + 38.4 in²
Surface area = 81.2 in²
The surface area of the rectangular box is 81.2 square inches.
