A 30 m by 30 m square. Each of the tiles is 20 cm by 20 cm [20 cm = 0.20 m]. So 30 m / 0.20 m = 150. So you need 150 x 150 = 22500 tiles
100 cm = 1 m so 20 cm = 20/100 m = 0.2 m. Simple!
By unit of length and distance and conversion ,we can say that 1 m=100 cm 20 m=200 cm
There are 20 cm in 0.2 m.
1 m = 100cm100/20= 5 times.
9 m 20 cm - 7 m 30 cm = 9.2 m - 7.3 m = 1.9 m = 1 m 90 cm
No. 2 m = 200 cm
By unit of length and distance and conversion ,we can say that 1 m=100 cm 0.2 cm=20 m
about 20 cm in length
0.2 metres is 20 cm - which is 200 mm
1
0.4 m = 40 cm 0.2 m = 20 cm 0.7m = 70 cm Volume is 40 cm x 20 cm x 70cm = 800 cm^2 x 70 cm = 56000 cm^3
