Given,

Length= 1 m

Breadth= 1 m

Depth= 1 m

Dry Volume = 1 m³

Wet mix volume = 1 x 1.54 m³

( Wet concrete is 54%-57% more because there is loss during preparation and also concrete contracts after drying)

For M20 Concrete

Cement : sand : aggregate = 1 : 1.5 : 3

Sum of all ratios = 1+1.5+3 = 5.5

Cement

Quantity of cement = (cement ratio / Sum of ratios ) * Dry volume
= (1 / 5.5 ) * 1.54
= 0.28 m³

The density of cement = 1440 kg/cub.m

Mass of cement = Volume of cement * Density
= 0.28 * 1440
= 403.2 kg

We know that each bag of cement is 50 kg

Number of cement bags = 403.5/50 = 8 bags

Sand

Quantity of Sand = (Sand ratio / Sum of ratios ) * Dry volume
= (1.5 / 5.5 ) * 1.54
= 0.42 cub.m

Density of Sand = 1450kg/cub.m

Mass of sand = 0.42 * 1450 = 609 kg

Aggregate

Quantity of aggregate = (aggregate ratio / Sum of ratios ) * Dry volume
= ( 3 / 5.5 ) * 1.54
= 0.84 m³

The density of Aggregate: 1500 kg/ cub. m

Mass of Aggregate: 0.84 *1500 = 1260 kg

Assuming Water cement ratio = 0.5

then, Quantity of water = 0.5 * Cement bag* 50 kg
