Bricks
Openings in perforated bricks occupy 10%, and brick has dimensions of 30 cm, 15 cm, and 7.5 cm. Calculate
a) the weight of a perforated brick if you know that the density of the full brick material is p = 1800 kg/m3 (1.8 kg/dm3)
b) the number of perforated bricks allowed the driver to load on the truck with a load capacity of 5 tons and avoid car overload.
