The standard for conversion of metric (cm) to Imperial (inches) is
1 inch = 2.54 cm.
Hence 30 cm x 40 cm x 10 cm =
30/2.54 X 40 / 2.54 x 10 /2.54 =
11.811 ins. X 15.748 ins. X 3.937 ins.
As an approximation
12 ins. X 16 ins. X 4 ins.
2.54 cm = 1 in (exactly) 30 cm x 40 cm x 10 cm = (30 ÷ 2.54) in x (40 ÷ 2.54) in x (10 ÷ 2.54) in ≈ 11.811 in x 15.748 in x 3.937 in
40 cm x 40 cm x 30 cm = 48000 cm 48000 cm = 18897.637795275590551181102362205

25 centimeters is 9.84 inches.
no,30 centimeters is no taller then 4 decimeters . It is because 1 dm=10 cm 4 dm =40 cm and 40 cm> 30 cm
its smaller.
40 cm is about 15.748"
1200 cm square
40 inches is 101.6 cm
40 cm / 2.54 cm/inch = 16 inches
There are about 12 inches in 30 cm
30 inches = 76.2 centimeters.76.2 cm
