Find the Surface Area box (L)(L)(H)

Math
h=Ll=Lw=H
The surface area of a box is equal to the sum of the areas of each side of the box.
2⋅(length)⋅(width)+2⋅(length)⋅(height)+2⋅(width)⋅(height)
Substitute the values of the length l=L, the width w=H, and the height h=L into the formula.
2⋅L⋅H+2⋅L⋅L+2⋅H⋅L
Multiply L by L by adding the exponents.

Move L.
2LH+2⋅(L⋅L)+2⋅H⋅L
Multiply L by L.
2LH+2⋅L2+2⋅H⋅L
2LH+2L2+2HL
Add 2LH and 2HL.
Tap for more steps…
Move L.
2L2+2HL+2HL
Add 2HL and 2HL.
2L2+4HL
2L2+4HL
Find the Surface Area box (L)(L)(H)
