Answer:
Area of one square = 13.9876 ft²
Surface area of the cube = 83.9256 ft²
Step-by-step explanation:
Area of a square
[tex]\large\boxed{A=s^2}[/tex]
where s is the length of one side of the square.
From inspection of the given image:
Substitute the value of s into the formula and solve for area:
[tex]\implies \sf Area\;of\;one\;square=(3.74)^2=13.9876\;ft^2[/tex]
The surface area of a cube comprises six congruent square sides.
[tex]\implies \sf Surface\;area\;of\;cube=6 \times 13.9876=83.9256\;ft^2[/tex]
