Answer:
The correct answer is the Pyramid II has a volume 63 cubic inches
Step-by-step explanation:
Formula:-
Volume of pyramid = 1/3(base area* height)
To find the volume of pyramid I
Length = 7 in
Breadth = 3 in
Height = 8 in
Base area = Length * breadth = 7 * 3 = 21 square inches
Volume = 1/3(base area* height) = 1/3(21 * 8) =56 cubic inches
To find the volume of pyramid II
Length = 6 in
Breadth = 3.5 in
Height = 9 in
Base area = Length * breadth = 6 * 3.5 = 21 square inches
Volume = 1/3(base area* height) = 1/3(21 * 9) = 63 cubic inches
Therefore the correct answer is the Pyramid II has a volume 63 cubic inches
