18. The mass of a solid can be found by multiplying the solid's density by the volume of space the solid takes up . If the density of cement is 3150kg/m^3 a. Determine the density of cement in units of g/cm^3 b. Create a linear equation for the mass,, in kg, of a block of cement as a function of its volume, in m^3 . Remember the density of cement is 3150kg/m^3

a. To convert the density of cement from to , we use the following conversion factors:1 kg = 1000 g 1 m = 1000000 cm Given that the density of cement is 3150 kg/m , we can convert it as follows: b. The mass of a block of cement can be expressed as a linear function of its volume using the formula: Given that the density of cement is 3150 kg/m , the equation for the mass (in kg) as a function of the volume (in m ) is: Thus, the linear equation is:
