Answer:

Step-by-step explanation:
step 1
Find the volume of the cuboid
The volume is equal to

step 2
Find the mass of the cuboid
Remember that
The density is equal to divide the mass by the volume
so
The mass is equal to multiply the volume by the density

step 3
Find the mass of the square base pyramid
subtract the mass of the cuboid from the total mass

step 4
Find the volume of the pyramid
The volume is equal to

step 5
Find the density of the steel (pyramid)
divide the mass of the pyramid by the volume of the pyramid
