Three cubes of each side 4 cm are joined end to end. Find the surface area of the resulting cuboid.
Answers
The surface area of the resulting cuboid is 224 cm².
Step-by-step explanation:
Given : each side of the cube is 4 cm.
When three cubes are joined end to end, then the resulting solid is a cuboid.
Length of the cuboid,( l) = 3 × each side of the cube = 3 × 4 cm = 12 cm
Breadth of the cuboid,(b) = each side of the cube = 4 cm
Height of the cuboid, (h) = each side of the cube = 4 cm
Surface area of the cuboid = 2 (lb + bh + hl)
= 2 (12 cm × 4 cm + 4 cm × 4 cm + 4 cm × 12 cm)
= 2 (48 + 16 + 48) cm
= 2 × 112 cm²
= 224 cm²
Hence, the surface area of the resulting cuboid is 224 cm².
