Question

Fill in the blank in the following so as to make the statement true:

The volume of a wooden cuboid of length 10 cm and breadth 8 cm is 4000 cm³. The height of the cuboid is ........ cm.

Answer 1

\[\text { Lenght of the wooden cuboid = 10 cm }\]

\[\text { Breadth = 8 cm }\]

\[\text { Its volume = 4000 } {cm}^3 \]

\[\text { Suppose that the height of the cuboid is h cm}. \]

\[\text { Then, volume of the cuboid = length } \times \text { breadth  }\times\text {  height }\]

\[ \Rightarrow 4000 = 10 \times 8 \times h \]

\[ \Rightarrow 4000 = 80 \times h \]

\[ \Rightarrow h = \frac{4000}{80} = 50 cm\]
