Cuboid

$l$ = 10        (length of Cuboid)
$w$ = 1        (width of Cuboid)
$h$ = 1        (height of Cuboid)
$v = l \cdot w \cdot h =$ 10

Tetrahedron

$l$ = 10        (length of Tetrahedron)
$w$ = 1        (width of Tetrahedron)
$h$ = 1        (height of Tetrahedron)
$v = l \cdot w \cdot h / 6 =$ 1.6666666666666667

Sphere

$r$ = 1        (radius of sphere)
$v = \frac{4}{3} \pi \cdot r^3 =$ 4.1887902047863905
