Part A: what tool can help Jada find possible dimensions for the base of the block? Explain.
I am not sure what a "tool" is by their wording, but we can use the formula for volume to solve for the base.
-> B is the base, length times width, and H is the height
V = B * H
350 in³ = B * 5 in
70 in² = B
Answer: The base will be 70 in²
Part B: Give one pair of possible whole-number dimensions for the base.
Since we know the base will be 70 in², we can find a possible pair of whole-number dimensions for the base.
B = L * W
70 in² = L * W
Now we just need to find pairs of whole numbers that multiply to 70:
70 / 2 = 35
Answer: A possible pair of whole-number dimensions for the base is 2 and 35.
