Question

A wooden box 2 m long, 1 m wide and 50 cm deep is open at the top. Determine the cost of wood required for it,if 1 sq.m of wood costs rs 10 .​

Answer 1

Answer:

Step-by-step explanation:

We need to do By taking Lateral Surface Area of Cuboid.

Formula= 2(Length+Breath)×Height.

Solution= 2×(2+1)×0.50 {Convert 50 cm into metre}.

2×3×0.50

3m² is LSA or 4 sides of box.

Now 1 side area of box = Length×Breath.

2×1=2m²

Now Area of 5 sides =3+2m²=5m²

Now total cost of wood = 5×10=50ruppes
