A rectangular cardboard is 65 cm long and 45 cm wide.

Question

A rectangular cardboard is 65 cm long and 45 cm wide. What is the maximum number of rectangles, each 12 cm long and 8 cm wide that can be cut from it?

Answer 1

Cutting the 12 cm side from the

65 cm length... 65/12 = 5 5/12 pieces

 

so we can get 5 lengths of 12 from

one dimension leaving a 5cm piece

 

For the width: 45 cm ÷ 8 cm = 5 5/8

 

So we can get 5 of the 12x8 cm

rectangles leaving an L shaped piece

of 5 cm width
