6 0

You have a 1/3 chance each time you role So 1/3 x 12 = 4 times that you would role a 5 or a 6

What is the volume of a cube with length of 10cm, the width of 5cm and a height of 8cm?

lubasha [3.4K]

400 cm³

<h3>Further explanation</h3>

<u>Given:</u>

Length = 10 cm
Width = 5 cm
Height = 8 cm

<u>Question:</u>

What is the volume of a cuboid?

<u>The Process:</u>

We use the formula for cuboid volume:

$\boxed{ \ V = length \times width \times height \ }$ or $\boxed{ \ V = l \times w \times h \ }$

Let us calculate the volume of cuboid.

$\boxed{ \ V = 10 \times 5 \times 8 \ }$

Thus, the volume of cuboid is 400 cm³.

Notes:

A cuboid is a 3D shape. Another name is a rectangular prism. Unlike the cube, the sides of a cuboid are unequal lengths. However, the way to calculate the volume of cuboid and cube is the same, i.e., multiplying the three lengths of the sides. The other thing is to calculate the surface area by adding up all the sides.
