Question

a rectangle cardboard sheet has length 32 cm and breadth 26 cm.squares each of side 3 cm, are cut from the corners of the sheet and the sides are folded to make a rectangular container. find the capacity of the container formed.

Answer 1

In rectangle
length = 32cm
breadth = 26cm
height = 3cm (as length of square is 3cm)

volume of rectangle = lbh
= 32*26*3
= 2496 cm sq

Answer 2

Given,
Length of rectangle = 32cm
Breadth of rectangle = 26cm

Length of figure after cutting the squares = 32 - 6(length of both squares) = 26cm
Breadth of figure after cutting the squares = 26 - 6(breadth of both squares)=20cm

After folding the sheet, 
Length of container = 26cm
breadth of container = 20cm
height of container = 3cm

Therefore, volume of container = lbh = 26cm X 20cm X 3cm = 1560cm square
