10 Select the correct answer. Annle is baking a square-shaped cake for her sister's birthday. She Is expecting 18 guests. She plans to cut the cake into square-shaped pieces 2 inches long. The cake must be big enough so each guest gets 2 pieces. What must the length of the cake be for each guest to get 2 pleces each? A. 6 inches B. 12 inches C. 36 inches D. 72 inches

## Step 1<br />First, we need to calculate the total number of pieces that Annle needs to cut the cake into. Since each guest is expected to get 2 pieces, and there are 18 guests, the total number of pieces needed is \(18 \times 2 = 36\).<br /><br />## Step 2<br />Next, we need to find out the length of the cake. Since the cake is cut into squares that are 2 inches long, and we need 36 pieces, the length of the cake must be \(36 \times 2 = 72\) inches.
