Question

5 cubes each of side 2 units are joined together. Find the resulting volume.

• A. 8 cubic units
• B. 10 cubic units
• C. 40 cubic units
• D. 80 cubic units

Answer 1

The correct option is C 40 cubic units

Since the cube is of side 2 units and they are placed or joined together , we have a cuboid of length 10 units , breadth 2 units and height 2 units as shown in the figure given below

The volume of the cuboid = $length\times breadth\times height$
= $10\times 2\times 2$
= 40 cu units
