Answer:
A. It does not matter. The volumes of X and Y are equivalent.
Step-by-step explanation:
Volume of the pyramid = Base area × Height
For rectangular pyramid X:
Given Height of pyramid = 10cm
Base area = Length × Breadth
Base Area = 6cm×5cm = 30cm²
Volume = 10×30
Volume of the pyramid = 300cm²
For pyramid Y:
Given Height = 10cm
Base area = 1/2 base×height
Base area ,= 1/2 × 7.5×8
Base area = 30cm²
Volume of the triangular pyramid = 10×30 = 300cm³
We can see that the volume of X and Y is the same, therefore the type of chocolate Jeremy chose doesn't matter.
