Question

find the total surface area of cuboids of length,breadth and height
2.5m,2m,2.4m
​

Answer 1

2(lb+bh+lh)= 2(2.5*2+2*2.4+2.5*2.4)=2(5+4.8+6)=2(15.8)=31.6m^2

Answer 2

Answer:

Area of cuboid=2 ( l × b ) + ( b× h ) + ( l× h )

                        =2 (2.5 x 2) + (2 x 2.4)+(2.5 x 2.4)

                        =2 ( 5 +4.8+6)

                        =2(15.8)

                        =31.6 m2
