Question

The length, breadth and height of a cuboid are 10cm, 6cm, 4cm, Find its Lateral surface area and Total surface area.

Answer 1

Answer:

Lateral Surface Area = 2h(l+b) = 2(4)(10+6) cm² = 8(16) cm² = 128 cm²

Total Surface Area = 2(lb+bh+hl) = 2[(10)(6)+(6)(4)+(4)(10)] = 2[60+24+40] cm² = 2(124) cm² = 248 cm²
