Answer:
The total surface area of the box = 2336 cm²
Step-by-step explanation:
Given : Rectangular sheet size = 60 cm x 40 cm
Squares cut at corners = 4cm x 4cm
Solution : Original surface area of rectangle = length x breadth
= 60 x 40
= 2400 cm²
Square surface area = side x side
= 4 x 4
= 16 cm²
The total area of the box = Original surface area of rectangle - 4 x surface
area of square
= 2400 - 4 x 16
=2400 - 64
= 2336 cm²
