Question

Sneha wants to make a box. She starts with a piece of cardboard whose length is 30 cm and width is 25 cm.
Then she cuts squares with sides 2 cm each from the four corners.
What is the area of the card board left after she cuts the 4 corners?

Answer 1

Answer:

Subtract +3+ cm from each end of length

+15+-+2%2A3+=+9+ cm

Subtract +3+ cm from each end of width

+10+-+2%2A3+=+4+ cm

The height will be +3+ cm after the sides

are folded up

----------------

+9%2A4%2A3+=+108+

The volume is 108 cm3
