Question

find total surface area of cuboid whose:
length=10m
breadth=6.4m
height=5m​

Answer 1

Answer:

Length of cuboid = 10 m

Breadth = 6.4 m

Height = 5 m

T.S Area of a Cuboid = 2 ( lb + lh + bh )

                                  = 2 ( 10 x 6.4 + 10 x 5 + 6.4 x 5 )

                                  = 2 ( 64 + 50 + 32 )

                                  = 2 ( 146 )

                                  = 292 m²
