Question

1.If the thickness of a pile of cardboards is 44 mm, how many cardboards will be there in a pile which is 71.5 cm thick?​

Answer 1

Answer:

Thickness of 16 card boards = 44 mm .

Thickness of 1 card board = (44/16)

= (44/160) mm.

Then, thickness of 7.15 cm piles = (44/160) * 71.5 cm

= (44/160) * (71.5 * 10) mm

= (44/160) * 715 mm

= 260.

Therefore, 260 cardboards will be there in a pile.
