The formula for the surface area of a box is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Given that the base of the box has dimensions 4.5 mm x 5 mm, we can consider the length (l) to be 5 mm and the width (w) to be 4.5 mm. The height (h) is given as 1 mm.
Plugging in the values, we get:
Surface area = 2(5)(4.5) + 2(5)(1) + 2(4.5)(1)
Surface area = 45 + 10 + 9
Surface area = 64 mm^2
Therefore, the surface area of the box is 64 mm^2.
base = 4.5 mm x 5 mm
height = 1 mm
what is the surface area of the box?
