Question

Find the volume ,the total surface area and the lateral surface area of a cuboid which is 8 m long, 6m broad and 3.5m high.

Answer 1

Tsa of cuboid = lb+bh+lh
48+21+28=97

Answer 2

Length= 8 m
Breadth= 6 m
Height= 3.5 m
Now,
Volume= lbh= 8*6*3.5= 168 m^3
Lateral Surface Area= 2(l+b)h= 2(8+6)3.5= 9.8 m^2
Total Surface Area= 2(lb+bh+hl)= 2(8*6+6*3.5+8*3.5)= 2(48+21+28)= 2*97= 194 m^2
