Answer:
- Length of wall = 8 m
- Breadth of wall = 4.5 m
- Side of square marble stone = 30 cm
- Rate of each stone = Rs. 25
First change unit of wall into centimetres
- Length = (8 × 100) = 800 cm
- Breadth = (4.5 × 100) = 450 cm
• Number of marble stone required :
⇒ Area of wall = Area of 1 stone × Number
⇒ (Length × Breadth) = (Side)² × Number
⇒ (800 cm × 450 cm) = (30 cm)² × Number
⇒ 360,000 cm² = 900 cm² × Number
⇒ 360,000 cm²/900 cm² = Number
⇒ Number = 400
⠀⠀⠀⠀⠀───────────────
• Cost of covering wall with marble :
⇒ Cost = Number of marble required × Rate
⇒ Cost = 400 × Rs. 25
⇒ Cost = Rs. 10,000
∴ It will cost Rs. 10,000 to cover the wall with marble stone.
