A rectangular metal block with side 1.5𝑚 by 1.2𝑚 by 1.0𝑚 rests on a horizontal surface .If the density of
the metal is 7000𝑘𝑔/𝑚3, calculates; i. Volume of the metal block, ii. Mass of metal block, iii. The
difference between maximum and the minimum pressure that the block can exerts on the surface

volume = 1.5m*1.2m*1.0m = 1.8 m^3
mass = volume * density

since pressure = force/area,
maximum pressure is when the smallest face is resting on the surface
minimum pressure is when the largest face is resting on the surface.
I assume you know how to find the area of a rectangular face.

remember weight = mass * g
and as you know pressure = weight in Newtons / area in square meters
