Question

A cuboid has dimensions 10cm X 10cm X 5cm

Work out the surface area of the cuboid.

Answer 1

Answer:

A solid all of whose sides are rectangles are cuboids. Cuboid is a 3-dimensional shape or a polyhedron, having 6 rectangular sides called faces. It has 8 vertices and 12 edges. Each face is a rectangle and all the cuboids corner are vertices are 90-degree angles.

Total surface area of a cuboid = Sum of the areas of all its 6 rectangular faces

= 2(lb + bh +lh)

=2(10*10+10*5+10*5)=400 cm^2

Answer 2

Step-by-step explanation:

Given l= 10cm, b= 10cm , h= 5cm

Total surface area of the cuboid=2(lb+bh+hl)

= 2(10x10+ 10x5+ 5x10)

= 2(100+50+50)

= 2(200)

= 2x200= 400cm²
