.27 x .27 x.48 = .035 cum.

1000 litre = 1 cum.
35 litres = 1/1000 x 35 = .035 cum.

0.27 x 0.27 x 0.48 = 0.035cum = 35 liters.

What is forma? Anyone explain it.

Actually, it is 31 * 31 * 52cm.

No, @Devaraj.

It is 27 X 27 X 48.

35 litres are chosen because, while doing nominal mixing ( like for M15 at 1:2:4) etc, the volume of 1 in cement represents 1 bag of cement which is of 0.035m3 which in turn is 35 Litres.

So, the volume of container measuring should also be 35 Litres.
Hence, the containers volume L * B * H.
which is 27 * 27 * 48 which gives 35000ml => 35 L.
The answer given in key is correct.

@Devraj.

For measuring, 50 liters of the aggregate form should be .31*.31..52 = 50 liters.
