Question

The size of a brick is 25cm x 12 cm x 55cm and its density is 1.8 x10^3 kg/m^3. How many trips must a 3-ton dumper carry out to transport 15,000 bricks to a construction site?

Answer 1

alright you'll need this equations

\[\rho=\frac{m}{v}\]
where \[\rho=density,m=mass,v=volume\]
and
how many kg's a ton is

Answer 2

first lets find out the mass of one brick

we need volume... however we have density in meters and bricks in centimeters so we have to switch all the values into meters
