Find the surface area of a box with dimensions 125mm *64mm*84mm to the nearest mm?

To find the surface area of a box, we need to calculate the area of each of its six faces and then add them together.

The formula for the surface area of a box is:
Surface Area = 2lw + 2lh + 2wh

Given dimensions:
l = 125mm
w = 64mm
h = 84mm

Substitute the values into the formula:
Surface Area = 2(125*64) + 2(125*84) + 2(64*84)
Surface Area = 2(8000) + 2(10500) + 2(5376)
Surface Area = 16000 + 21000 + 10752
Surface Area = 47752 mm^2

Therefore, the surface area of the box is 47752 mm^2.

Surface area of a box = 2(lb + bh + hl)

Given: l = 125 mm, b = 64 mm, h = 84 mm

Surface area of the box = 2(125 x 64 + 64 x 84 + 125 x 84)

= 2(8000 + 5376 + 10500)

= 2(23876)

= 47752 mm

Therefore, the surface area of the box to the nearest mm is 47752 mm.
