How to Solve: The Surface Area Formula
Formula for a Rectangular Prism:
\( SA = 2(lw + lh + wh) \)
\( l \) = length
\( w \) = width
\( h \) = height
EXAMPLE: \( l=5, w=2, h=3 \)
Find Front/Back: \( 5 \times 3 = 15 \times 2 = 30 \)
Find Top/Bottom: \( 5 \times 2 = 10 \times 2 = 20 \)
Find Sides: \( 2 \times 3 = 6 \times 2 = 12 \)
Add them all: \( 30 + 20 + 12 = 62 \text{ units}^2 \)
