If a cuboid is 2.7cm high, 7.8cm long and 3.7 wide then volume of cuboid is

Answer: A

The volume of a cuboid is the product of its three dimensions.

\[ V = l \times b \times h = 7.8 \times 3.7 \times 2.7 \]

\[ 7.8 \times 3.7 = 28.86 \]

\[ 28.86 \times 2.7 = 77.922 \text{ cm}^{3} \]

Three decimal places appear in the answer because the factors contribute one each - a quick check that the decimal point has landed correctly.
