Question

an open box having length 1.5 m breadth 1m height 1m , how many sheet required to make box​

Answer 1

Answer:

Data :

• L = 1.5 m
• B = 1m
• H= 1m

The box has 5 rectangular sides

The dimensions of the 5 rectangles are :

1. 1.5×1 = 1.5 m²
2. 1×1 = 1m²
3. 1.5×1 = 1.5m²
4. 1×1.5 = 1.5m²
5. 1×1 = 1 m²

The area of sheet required is the sum of areas of all the rectangles

Area of sheet = 1.5+1.5+1.5+1+1 = 6.5

6.5 metres of sheet is required to make the box
