Question

Calculate the cost of the plastering required for a wall of 4 m long, 3.5 m high and 300 mm thick, if the rate of plastering is Rs. 12 per square meter.

Answer 1

Answer:

Step-by-step explanation:

Since the wall is cuboidal

Therefore surface area of cuboid =

2[ lb+bh+hl]

Now the next step will be to put up all the values given in the question in the above written formula so,

2[4*0.3+0.3*3.5+3.5*4]

= 32.5 m²

Therefore cost = 32.5*12= 390 rupees
