The image appears to show a math exercise related to the volume of a rectangular water tank.

Part (a):

To find the volume of the water tank, the formula for the volume of a rectangular prism is used:

$V = \text{length} \times \text{width} \times \text{height}$

In this case:

• Length = 12 cm
• Width = 8 cm
• Height = 5 cm

So, the volume calculation is:

$V = 12 \times 8 \times 5 = 480 \, \text{cm}^3$

Therefore, the water tank's capacity is 480 cm³, which is equivalent to 480 mL (since 1 cm³ = 1 mL).

Part (b):

This part is asking how many 1 cm³ cubes the water tank can hold. Since each cube has a volume of 1 cm³, the number of cubes the tank can hold is simply the volume of the tank, which is 480 cubes.

Summary:

• The water tank has a capacity of 480 cm³ (or 480 mL).
• The water tank can hold 480 1 cm³ cubes.
