Question

Part A : what is the area of one square. Part B : using the information you found in Part A , what is the surface area of the cube

Answer 1

Area of one square = 13.9876 ft²

Surface area of the cube = 83.9256 ft²

Explanation:

Area of a square

`\large\boxed{A=s^2}`

where s is the length of one side of the square.

From inspection of the given image:

• s = 3.74 ft

Substitute the value of s into the formula and solve for area:

`\implies \sf Area\;of\;one\;square=(3.74)^2=13.9876\;ft^2`

The surface area of a cube comprises six congruent square sides.

`\implies \sf Surface\;area\;of\;cube=6 * 13.9876=83.9256\;ft^2`
