The object on the right is made from a square-based pyramid joined to a cuboid. the base of the cuboid and the base of the pyramid are both squares of side 6cm.
the bright of the cuboid is 9cm and the total height of the object is 17cm.
the total mass of the object is 970g.
the cuboid is made from wood with density 0.68g/cm^3
the pyramid is made from steel.
calculate the density of the steel in g/cm^3.
you must show your working.

Density of steel = 80.73 gm/

Step-by-step explanation:

The figure is made up of cuboid and square pyramid.

Height of cuboid, h = 9 cm

Length of cuboid, l = 6 cm

Width of cuboid, w = 6 cm

Volume of cuboid is given by the formula:

Density of Wood , = 0.68g/

We know that formula of Density is:

Putting the values:

Total weight =

970 = 220.32

= 749.68 gm

Volume of pyramid is given as:

Base is a square with side 6 cm

Density of Steel/Pyramid:
