To calculate cement and sand for 1 sqm cm 1:4, use the formula: (1/5.5) * 1 = 0.18 cubic meters of cement and (4/5.5) * 1 = 0.73 cubic meters of sand.

• The ratio of cement to sand is 1:4

• Calculate the total volume of the mixture, which is 1 sqm cm

• Divide the total volume by the sum of the ratio (1+4=5)

• Multiply the quotient by the individual ratio to get the volume of cement and sand

• Convert the volume to weight using the de
