Question

An open tank is 13 m long 9whole 1/2 m wide and 8 m deep.Find the cost of plastering the inside at rs4 whole 1/2 per m²​

Answer 1

Answer:

The cost for plastering the inside would be 2175.75 rs.

Step-by-step explanation:

Length = 13m

Breadth = 9whole 1/2 m = 9.5m

Height = 8m

Rate of plastering = 4 whole 1/2 rs. = 4.5 rs per sq.m.

Cost of plastering the inside = 4.5× lateral surface area of tank+ Base area of tank

So, cost = 4.5× 2(13+9.5)8 + 13×9.5

= 4.5 × (16×22.5) + 123.5

= 4.5 × 360.0 + 123.5

= 4.5 × 483.5

= 2175.75 rs.

Answer 2

Answer:

so,cost = 4.5×2 (13+9.5) 8+13×9.5

= 4.5×(16×22.5)+ 123.5

= 4.5× 360.0+123.5

= 4.5 × 483.5

= 2175.75
