Question

cost of painting and open ground tank of size 3 metre into 2 metre into 1.5 metre at rupees 50 per metre square is​

Answer 1

ANSWER

Given:

Dimensions of the tank :

Length ( l ) = 3m

Breadth ( b ) = 2m

height ( h ) = 1.5 m

Total surface area = 2( lb + bh + lh )

= 2 [ 3 ×2 + 2 × 1.5 + 3 × 1.5 ]

= 2 ( 6 + 3 + 4.5 )

= 2 × 13.5

= 27 m²

Cost of painting 1 sq metre = Rs 20

Cost of painting 27 square meters

= 20 × 27

= Rs 540
