Identify the lateral area and the surface area of a cube with edge length 15 in.

Sagot :

The Lateral area of the cube = 900 in.²

The Surface area of the cube = 1,350 in.².

What is the Lateral Area of a Cube?

A cube's lateral area is the area covered by the lateral surfaces of the cube shape. The formula for the lateral area of a cube is given as: LA = 4a², where:

a = edge length of cube.

What is the Surface Area of a Cube?

The surface area of a cube is the total area of all its 6 surfaces. The formula for finding the surface area of a cube is: 6a², where:

a = edge length of cube.

Edge length of cube (a) = 15 in.

Lateral area = 4a² = 4(15²)

Lateral area = 4(225)

Lateral area of the cube = 900 in.²

Surface area = 6a² = 6(15²)

Surface area = 6(225)

Surface area of the cube = 1,350 in.².
