Question

A box measures 30 cm x 15 cm x 10 cm. How many tiles having length
of 10 cm. breadth of 9 cm and height of 2 cm can be arranged in this
box​

Answer 1

Answer:

Length of the floor=18m=18X100=1800cm

Breadth of the floor=15m=15X100=1500cm

Area of the floor =l X b=1800 cm X 1500 cm

Area of the tile =side X side=30cm X cm

total number of tiles=Area of the floor/Area of the tile

Number of tiles =(1800 cm X 1500 cm)/ (30 cm X 30 cm)=3000 tiles

Cost of one tile = Rs 2.50

Total cost of 3000 tiles = Rs 2.50 X 3000 =Rs 7500 answer
