The formula for calculating the surface area of a rectangular box is:
Surface Area = 2lw + 2lh + 2wh
Given:
Length (l) = 4m
Width (w) = 3m
Height (h) = 1.5m
Substitute into the formula:
Surface Area = 2(4)(3) + 2(4)(1.5) + 2(3)(1.5)
Surface Area = 24 + 12 + 9
Surface Area = 45 square meters
Therefore, the surface area of the box is 45 square meters.
base = 4 m x 3 m
height = 1.5 m
what is the surface area of the box?
