Answer: Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve
Y = 16 because 4x3 = 12 + 4 = 16
The volume of a cube = e^3
e = a single edge of the cube.
Area of a square = a^2
a = a single side of the square.
The volume of our cube = 13 ft^3
e = ![\sqrt[3]{13}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B13%7D)
= 2.35 ft
The area of our square = 4 ft^2
a = 
= 2 ft
The edge of our cube is greater than the length of our square's side.
