Answer 2

Step-by-step explanation:

A cardboard box measures 4cm x 1.5 cm x 7 cm. What is the area of the

cardboard needed to make the box?

=== length =4

breath=1.5

height=7

total surface area of cuboid = 2(lb +lh+bh)

let's substitute the value

2(4*1.5 +4*7 +1.5*7)

2(6+28+10.5)

2(44.5)

89cm²

therefore the area of of cardboard needed to make the box is 89 cm²
