Question

Five identical cubes, each of edge 5 cm, are placed adjacent to each other. Find the volume of the resulting cuboid.

Answer 1

$$\begin{gathered} \mathrm{We}\mathrm{have}, \\ \mathrm{Length}\mathrm{of}\mathrm{the}\mathrm{resulting}\mathrm{cuboid},l=5\times 5=25\mathrm{cm}, \\ \mathrm{Breadth}\mathrm{of}\mathrm{the}\mathrm{resulting}\mathrm{cuboid},b=5\mathrm{cm}\mathrm{and} \\ \mathrm{Height}\mathrm{of}\mathrm{the}\mathrm{resulting}\mathrm{cuboid},h=5\mathrm{cm} \\ \mathrm{Now}, \\ \mathrm{Volume}\mathrm{of}\mathrm{the}\mathrm{resulting}\mathrm{cuboid}=lbh \\ =25\times 5\times 5 \\ =625{\mathrm{cm}}^3 \end{gathered}$$

So, the volume of the resulting cuboid is 625 cm³.
