Question

a.
:) Find the volume ond the total surface area of a cuboid whose dimension
are 3m, 70cm and 50cm​

Answer 1

Answer:

Volume of Cuboid = length x breadth x height

considering length = 3m,

converting breadth and height into metres

breadth = 0.7 m

height = 0.5 m

As per formula given above;

lxbxh = 3 x 0.7 x 0.5

= 1.05 cubic meter

Total Surface Area = 2 (lb+bh+hl)

= 2 ((3*0.7)+(0.7*0.5)+(0.5*3))

= 2 (2.1+0.35+1.5)

= 2 (3.95)

= 7.9 m

Hope this solves your question
