The total surface area of a cuboid is 236 cm 2. Its length is 8 cm and height is 6 cm. Find its breadth (in cm).
5
Given:
Total surface area = 236 cm2, Length = 8 cm, Height = 6 cm.
Formula:
Total surface area = 2(Length × Width + Length × Height + Width × Height)
Evaluation:
236 = 2(8 × B + 6 × B + 8 × 6)
⇒ 118 = 8B + 6B + 48
⇒ 70 = 14B
⇒ B = 70/14 = 5 cm
