The surface of a cube is 13 1/2 cm squared. how long is one side of the cube

A cube has 6 sides. Divide the surface area by 6 to get the area of one side:

13 1/2 /6 = 2 1/4

The area of one side is S^2

To fins the length of the sides find the square root of the area:

Side = sqrt(2 1/4)

Side = 1 1/2 cm.

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
