Answer:

───────────────────────────

1) Area of sheet which is required to box is 5.45m²

2) Cost of sheet is Rs.109

────────────────────────────

Given:-

• Length of box = 1.5m
• Breadth of box = 1.25 m
• Height of box = 0.65

Find:-

• Area of sheet which is required for box?
• Cost of sheet if a sheet measuring 1m² costs Rs.20.

Solution:-

(1) Area of sheet required for box:-

${ \boxed{ \sf{Area \: of \: sheet \: required =2lh + 2bh + lb}}}$

${ \to{2 \times 1.5 \times 0.65 + 2 \times 1.25 \times 0.65 + 1.5 \times 1.25}}$

${ \to{1.95 + 1.625 + 1.875}}$

${ \to{5.45}}$

Area of sheet required for box is 5.45m²

(2)Cost of sheet:-

Cost of 1m² area = Rs. 20

Cost of 5.45m² area sheet = 20 × 5.45

Cost of 5.45m² area sheet= Rs.109

Cost of sheet is Rs. 109
