Question

two cubes each sides 6cm are joined end to end .find the volume of the resulting cuboid

Answer 1

Volume of  one cube = 6 cm * 6 cm * 6 cm = 216 cubic cm

Two cubes are joined face to face.  So their volumes are joined.  The

Volume of the resulting cuboid = 216 * 2 = 432 cubic cm.
=============================
Or,  another way,  the dimension along which the cubes are joined is 6 cm + 6 cm = 12 cm.

Volume of cuboid are = 12 cm * 6 cm * 6 cm = 432 cubic cm

Answer 2

Volume of  one cube = 6 cm × 6 cm × 6 cm = 216 cubic cm

Volume of the resulting cuboid = 216 + 216 = 432 cubic cm.

The dimension along which the cubes are joined is 6 cm + 6 cm = 12 cm.

Volume of cuboid are = 12 cm × 6 cm × 6 cm = 432 cubic cm
