Question

length ofcuboid is2m10cm breadth is 1m hight is 80cm find the area of cuboid

Answer 1

Length = 2 + 10/100 = 2 + 1/10 = 2.1

Breadth = 1 m

height = 80 cm = 80/100 m = 0.8 m

Area of cuboid = 2( lb + bh + hl)

= 2( 2.1 × 1 + 1× 0.8 + 0.8 × 2.1)

= 2( 2.1 + 0.8 + 1.68 )

= 2( 4. 58)

= 9.16 m^2

Answer 2

Answer: 9.16 m sq

Step-by-step explanation:

Given l = 2m 10 cm = 210 cm = 2.1 m

b = 1m

h = 80 cm = 80/100 = 0.8 m

Area of cuboid = 2( lb + bh + hl)

= 2( 2.1 × 1 + 1× 0.8 + 0.8 × 2.1)

= 2( 2.1 + 0.8 + 1.68 ) 

= 2( 4. 58)

= 9.16 m^2
