Answer 1

the volume of the cut-out is 200 cm³

Explanation:

Given;

length of each side of the square cardboard, L = 10 cm

the thickness of the cardboard, h = 2 cm

The volume of the cut-out = area of the square cardboard x thickness of the cardboard

The volume of the cut-out = L² x h

The volume of the cut-out = 10 cm x 10 cm x 2 cm

The volume of the cut-out = 200 cm³

Therefore, the volume of the cut-out is 200 cm³
