To find the volume of a rectangular block, you can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
For the cheese block, the dimensions are:
- Length = 10 cm
- Width = 5 cm
- Height = 3 cm
Now, substitute the values into the formula:
\[ \text{Volume} = 10 , \text{cm} \times 5 , \text{cm} \times 3 , \text{cm} \]
Calculating this:
\[ \text{Volume} = 10 \times 5 \times 3 = 150 , \text{cm}^3 \]
Therefore, the volume of the block of cheese is \( 150 , \text{cm}^3 \).
