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:
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
