Answer #1

The metal given here is in the shape of a rectangular block. So the density of the metal will be mass of the metal by volume of the metal block.

d = Density of the given substance

m = Mass of the given substance

V = Volume of the given substance

The volume of the metal block will be equal to the volume of its shape that is cuboid.

Volume of cuboid = length × breath × height

V = l×b×h

V = 10 × 6 × 2 = 120 cm3.

Now density of metal, d = m /v

Here, m = 3701g and v = 120 cm3

Substituting the values of m and v in the equation for density, the equation becomes

d = 30.481 g/cm3

Find the volume of the largest rectangular box with edges parallel to the axes that can be inscribed in the ellipsoid x^2/9+y^2/36+z^2/1=1 Hint: By symmetry, you can restrict your attention to the first octant (where x,y,z≥0), and assume your volume has the form V=8xyz. Then arguing by symmetry, you need only look for points which achieve the maximum which lie in the first octant. Maximum volume:
