A paving block is is in the shape of a prism, the area of it' cross section being 154cm^2.The prism i 17cm long ad the material from whih it is made has a density of 2.2g/cm^3. Calculate the mass of the paving block.

Please can you tell me the method aswell

thanks

  • maths -

    Volume of prism
    = cross-sectional area * height
    = 154 cm2 * 17 cm
    = 2618 cm3
    Density = 2.2 g / cm3

    Mass
    = volume * density
    = 2618 cm3 * 2.2 g / cm3

    = 5759.6 g
    = 5760 g (approx.)
