Question

1. Find the volume and surface area of a cuboid whose dimensions are :
(b) length = 10.5m, breadth = 5m, height = 220 cm.



​

Answer 1

Answer:

115,500,000 cm³ ; 1,732,000 cm²

Step-by-step explanation:

Volume of Cuboid = (l×b×h)

= 1050 × 500 × 220    (all in cm)

= 115,500,000 cm³

Surface area of Cuboid = 2(lb+bh+lh)

= 2 [(1050×500) + (500×220) + (1050×220)]

= 1,732,000 cm²

Answer 2

Answer:

115,500,000 cm³ ; 1,732,000 cm²

Step-by-step explanation:

Volume of Cuboid = (l×b×h)

= 1050 × 500 × 220    (all in cm)

= 115,500,000 cm³

Surface area of Cuboid = 2(lb+bh+lh)

= 2 [(1050×500) + (500×220) + (1050×220)]

= 1,732,000 cm²
