Question

Ally made a net to find the surface area of a box she was designing. The box measure 12 centimeters long by 9 centimeters high by 9 centimeters deep. What is the surface area, in square centimeters, of the box?

Answer 1

using the formula for the surface area of a box(cuboid) .
formula is

`2(height * width) + 2(height * length) + 2(width * length)`
2(h*w)+2(h*l)+2(w*l)
here we will take the word used in the question "deep" to be its width..
→2(9*9) + 2(12*9) + 2(9*12)
=594cm²
