Question

the formula for cell d2 is shown in the spreadsheet. use the data shown in row 3 to write a formula for cell a3. choose the correct formula for cell a3. a =b3c3/d3 b =d3/b3c3 c =b3-c3d3 d =d3/(b3c3)

Explanation:

Step1: Analyze the formula pattern

The formula for cell D2 is \( = A2 * B2 * C2 \), which calculates the volume (length width height). For cell A3, we need to reverse - engineer from the volume formula. The volume formula is \( Volume = length\times width\times height \), so \( length=\frac{Volume}{width\times height} \). In spreadsheet terms, if D3 is the volume, B3 is the width, and C3 is the height, then the formula for A3 (length) should be \( =\frac{D3}{B3\times C3} \) or in spreadsheet formula syntax \( =D3/(B3*C3) \). Let's check the options:

• Option A: \( =B3*C3/D3 \) is \( \frac{B3\times C3}{D3} \), which is not length.
• Option B: \( =D3/B3*C3 \) is \( \frac{D3}{B3}\times C3 \), incorrect.
• Option C: \( =B3*C3*D3 \), incorrect.
• Option D: \( =D3/(B3*C3) \), which matches our derived formula.

Answer:

D. \( =D3/(B3*C3) \)
