Question

A cube-shaped item needs to be painted The Item's edge length is 8 inches. What is the total surface area that has to be painted? Enter your answer as a number only; no units.

Answer 1

Answer:

384 Square Inches.

(You are required to enter only 384)

Step-by-step explanation:

Given a cube-shape item with an edge-length, s= 8 inches.

For it to be painted, we require the total surface area of the cube.

Total Surface Area of a Cube$=6s^2$

Therefore, the total surface area of the item

$=6*8^2\\=6*64\\=384 \:square \:inches$

The total surface area that has to be painted is 384 Square Inches.

Answer 2

Answer:

Step-by-step explanation:

The surface area of a cube = 6L^2 where L is the length of the side of each edge of the cube.

Noting that all sides of a cube are equal, so "L" is just the length of one side of a cube.

Therefore, Total surface area = 6L^ 2 = 6 * 6^2 = 6 * 36 = 216

So the total area of the cube

= 216
