all i know is that its a surface area problem which i suck at so

448 in²

Step-by-step explanation:

The amount of wrapping paper needed is the same as the surface area.

The shape is a rectangular prism.

Use the formula for the surface area of a rectangular prism.

SA = 2[(lw) + (hw) + (hl)]

l is for the length, w is for the width, h is for the height.

The dimensions are usually given as length x width x height.

l = 8

w = 8

h = 10

Substitute the values into the equation

SA = 2[(lw) + (hw) + (hl)]

SA = 2[(8*8) + (10*8) + (10*8)]   Simplify within each curve bracket

SA = 2[64 + 80 + 80]    Add within the square brackets

SA = 2[224]   Multiply

SA = 448    Final answer without units

The unit for area is the unit squared.

Therefore, 448 in² of wrapping paper is needed.
