# If two cardboard boxes occupy 500 cubic centimetres space, then how much space is required to keep 200 such boxes

**Solution:**

__Method 1:__

2 Cardboard Boxes occupy 500 cm³

Therefore one cardboard will occupy = 500/2 = 250cm³

Therefore 200 boxes will occupy = 250 × 200 = 50,000 cm³

__Method 2:__

Using the direct proportion method (also called Unitary method)

__Cardboard Boxes__ __Space__

2 500cm³

200 500 × (200/2) = 50,000 cm³

**✦ Try This: **If four cardboard boxes occupy 1600 cubic centimetres space, then how much space is required to keep 100 such boxes?

__Method 1:__

4 Cardboard Boxes occupy 1600 cm³

Therefore one cardboard will occupy = 1600/4 = 400cm³

Therefore100 boxes will occupy = 100 × 400 = 40,000 cm³

__Method 2:__

Using the direct proportion method (also called Unitary method)

__Cardboard Boxes__ __Space__

4 1600cm³

100 1600 × (100/4) = 40,000 cm³

Therefore space required to keep 100 boxes is 40,000 cm³.
