The cube edge length is 3 = cubic root of 27, so the square face has an area of 3*3 = 9. The cube is a hexahedron, so its total surface is 6*9 = 54.

area of a cube = l * w * h, cube root of 27 = 3, so length, width and height all equal 3. area of one square = 3 * 3 = 9 and there are 6 faces, so total surface area = 9*6 = 54 square inches

A cube has equal sides, so take the cube root of 27, and you will get 3 (3 * 3 * 3 = 27).
1 side = 3 * 3 = 9 sq. inches
There are six sides on a cube, which gives you:
6 * 9 = 54 sq. inches.

volume of a cube=(side)^3=27=3^3
so the side =3 in
also surface area of a cube=6(side)^2
=6(3)^2=6*9=54 sq in

cube = square where all sides are equal
volume of a cube = all three sides multiplied together
thus, cube root of 27 is 3
surface area of a cube is area of each side added together. A cube has six sides. 3*3 = 9, 9*6 = 54

the quantity is 27, or 3*3*3 cubic inches, so the size of one area must be 3 inches. the part of one area is 3 * 3, or 9 sq. inches, and the exterior are is 6 * 9 sq. inches, or fifty 4 sq. inches.

Cube root of 27 = 3
One side is 3 X 3 = 9 Sq. in.
6 sides = 54 sq.in.
