In geometry, a cuboid is a solid figure bounded by six faces. There are two competing incompatible definitions of a cuboid in the mathematical literature. the word “cuboid” is
sometimes used to refer to a shape of this type in which each of the faces is a rectangle this more restrictive type of cuboid is also known as a right cuboid, rectangular cube, or right
rectangular prism. **(Source wikipedia)**

**Problem 1**

Find volume and for rectangular cube, length of the rectangular cube is 22 mm, width of rectangular cube is 16 and height of the rectangular cube is 17 mm.

** Solution:**

Formula for volume of the rectangular cube v = l * h * w

Volume of rectangular cube = l * h * w

Where l = length of the rectangular cube

h = height of the rectangular cube

w = width of rectangular cube

Volume of the rectangular cube = 22 * 16 * 17

= 5984 mm^{3}

**Answer: **Volume of the rectangular cube = 5984 mm^{3}

**Problem 2**

Find volume for rectangular cube, length of the rectangular cube is 31 mm, width of rectangular cube is 14 and height of the rectangular cube is 17 mm

** Solution:**

Formula for volume of the rectangular cube v = l * h * w

Volume of rectangular cube = l * h * w

Where,

l =length of the rectangular cube

h = height of the rectangular cube

w= width of rectangular cube

Volume of the rectangular cube = 31 * 14 * 17

= 7378 mm^{3}

**Answer: **Volume of the rectangular cube = 7378 mm^{3}

**Problem 3**

Find volume for rectangular cube, length of the rectangular cube is 25 mm, width of rectangular cube is 22 and height of the rectangular cube is 20 mm

** Solution:**

Formula for volume of the rectangular cube v = l * h * w

Volume of rectangular cube = l * h * w

Where,

l =length of the rectangular cube

h = height of the rectangular cube

w= width of rectangular cube

Volume of the rectangular cube = 25 * 22 * 20

= 11000 mm^{3}

**Answer: **Volume of the rectangular cube = 11000 mm^{3}

**Problem 4**

Find volume for rectangular cube, length of the rectangular cube is 22 mm, width of rectangular cube is 20 and height of the rectangular cube is 26 mm

** Solution:**

Formula for volume of the rectangular cube v = l * h * w

Volume of rectangular cube = l * h * w

Where,

l =length of the rectangular cube

h = height of the rectangular cube

w= width of rectangular cube

Volume of the rectangular cube = 22 * 20 * 26

= 11440 mm^{3}

**Answer: **Volume of the rectangular cube = 11440 mm^{3}
