12 cm³ or 12 mL
Step-by-step explanation:
To find the volume of object A, we’ll use the formulae; L * W * H;
Where L = Length
W = Width
H = Height
Since all values are given, well just multiply them;
4 * 3 * 1 = 12 cm³
1 cubic centimeter is equivalent to 1 mL so we can also write the answer as 12 mL
