Answer:
Hey dear.... here is your answer...
Step-by-step explanation:
Given, each side of the cube is 5 cm.
When three cubes are joined end to end, then the resulting solid is a cuboid.
Length of the cuboid, l = 2 × each side of the cube = 2 × 5 cm = 10 cm
Breadth of the cuboid, b = each side of the cube = 5 cm
Height of the cuboid, h = each side of the cube = 5 cm
Surface area of the cuboid
= 2 (lb + bh + hl)
= 2 (10 cm × 5 cm + 5 cm × 5 cm + 5 cm × 10cm)
= 2 (50 cm2 + 25cm2 + 50 cm2)
= 2 × 125 cm2.
= 250 cm2.
Thus, the surface area of the resulting cuboid is 250 cm2.
