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.

To convert centimeters to inches, you can use the conversion factor of 1 inch = 2.54 cm. First, calculate the volume in cubic centimeters by multiplying 30 x 40 x 10 = 12,000 cm³. Then, convert this volume to cubic inches by dividing by (2.54)^3, which equals approximately 732.28 cubic inches.
40 cm / 2.54 cm/inch = 16 inches
30 cm = 11.811 inches 85 cm = 33.4646 inches
10 inches = 25.4 cm.
40 cm = 15.75 inches
110 cm is larger than 40 inches. To solve, convert to the same units; then they can be compared: 1 in = 2.54 cm (exactly) → 40 in = 40 × 2.54 cm = 101.6 cm < 110 cm → 110 cm is greater than 40 in.
