The rectangular prism is a three-dimensional solid that consists of six faces. Each face has a different surface area, and the surface area of a cube is the sum of all six faces. The volume of the solid is eighty-one cubic centimeters. In order to find the area of a PrismCubed, first calculate the area of each face. Once you've got the area of each face, you can figure out the minimum amount of gift wrap needed for it.
The basic unit of a cube is the square, which is three-dimensional and has six rectangular sides. The sides of a square are all square, and all angles meet at 90-degree angles. A cube has two v-vertices, a length of one side, and a width of two sides. A cube is a three-dimensional solid with all four sides the same length. Its surface area is equal to six times the length of any side.
A square prism has any two dimensions with the same measurement. The surface area of a cube or a prism can be calculated by using a surface area word problem. For example, a cube has a surface area of eighty-four square inches. In this example, the area of a cube or a rectangular prism is six feet, so a rectangle has a surface of eighty-four square inches.
