1cu meter (1m Height x 1m Width x 1m Length) + Weight (kg/ton) = 1 cu m kg/ ton 1cu meter of concrete (ready mix or site mix) approximately = 1920 kg = 1.92 ton
5cu meter of concrete (ready mix or site mix) approximately = 9600kg = 9.6 ton

1 sq meter (1m Height x 1m Width) 1 sq meter = 10,000sq cm (100cm x 100cm)
1cu meter of concrete can lay how many linear meter for the following kerb profiles?
a) " I "
1 cu meter of concrete can lay: 10,000sq cm / 421.875 sq cm = 23.7 linear meter run of kerbing
5 cu meter of concrete can lay: 23.7 linear meter x 5 = 118.5 linear meter run
b) " L "
A = 30 cm x 15 cm = 450 sq cm B = (7.5cm x 7.5cm) ---2 = 28.125 sq cm C = 10 cm x 30 cm = 300 sq cm D = (2.5 cm x 30 cm) ---2 = 37.5 sq cm
(A + C) – (B + D) = (450 sq cm + 300 sq cm) – (28.125 sq cm + 37.5 sq cm) = 750 sq cm – 65.625 sq cm = 684.375 sq cm
1 cu meter of concrete can lay : 10,000 sq cm / 684.375 sq cm = 14.6 linear meter run
5 cu meter of concrete can lay : 14.6 linear meter x 5 = 73 linear meter run
1sq m = 10cm x 100cm = 10,000 sq cm
400sq cm = 20cm x 20cm
100sq cm = 10cm x 10cm
