Question

Estimate the quantities of brickwork and plastering required in a wall 4m long, 3m high and 30 cm thick. Calculate also the cost if the rate of brickwork is Rs.32.00 per cu.m and of plastering is Rs. 8.50 per sq.m.

(a) Rs.1456.00

(b) Rs.1686.00

(c) Rs.1356.00

(d) Rs.1556.00

Answer 1

Right answer is (c) Rs.1356.00

The explanation is: Quantities of brickwork = LxBxH = 4m x 3m x 0.30m = 3.6 cu.m

Quantity of plastering (two faces) = 2 x 4m x 3m = 24sq.m

Cost of brickwork = 3.6 x 320.00 = Rs.1152.00

Cost of plastering = 24x 8.50 = Rs.204.00

Total cost = 1152.00 + 204.00 = Rs.1356.00.
