A brick wall is 5 m long, 3 m high and 0.23 m thick. Taking 500 bricks per m³ of brickwork, the number of bricks required is about:
सही उत्तर: ख) 1725
Volume = 5 × 3 × 0.23 = 3.45 m³; bricks = 3.45 × 500 = 1725.

Taking dry volume as 1.54 m³, the volume of sand required for 1 m³ of 1 : 1.5 : 3 concrete is:
सही उत्तर: घ) 0.42 m³
Sand = 1.54 × 1.5/5.5 = 0.42 m³ (coarse aggregate = 0.84 m³).

Taking dry volume as 1.54 m³ per m³ of concrete and one bag as 0.035 m³, the number of cement bags for 1 m³ of 1 : 1.5 : 3 concrete is about:
सही उत्तर: क) 8.0 bags
Cement = 1.54/(1 + 1.5 + 3) = 0.28 m³; bags = 0.28/0.035 = 8.0.

A nominal concrete mix of 1 : 3 : 6 is commonly used for:
सही उत्तर: ख) Plain cement concrete in foundation beds (M10)
1:3:6 (about M10) is a lean mix used for levelling courses and foundation beds, not for structural RCC.

The nominal mix proportion (cement : sand : aggregate) traditionally corresponding to M20 concrete is:
सही उत्तर: ग) 1 : 1.5 : 3
Traditional nominal mixes: M10 = 1:3:6, M15 = 1:2:4, M20 = 1:1.5:3, M25 = 1:1:2.

-
The cube rate estimate of a building is obtained by multiplying the cube rate by the:
सही उत्तर: घ) Plinth area × height of the building
Cube rate estimate = cubical contents (plinth area × height) × cube rate; it is more accurate than the plinth area method for buildings of varying height.

-
An approximate estimate of a hospital obtained by multiplying the number of beds by the cost per bed is based on the:
सही उत्तर: क) Service unit method
