How do you calculate the mass of a solid copper cuboid with a density of 9.86cm?

Step-by-step explanation:

The complete question is

How do you calculate the mass of a solid copper cuboid with a density of 9.86 g/cm^3. The dimensions of the cuboid are 10 cm  by 3 cm by 5 cm

step 1

Find the volume of the cuboid

step 2

Find the mass

we know that

To find out the mass multiply the density of the solid by its volume

so

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
