Final answer:
Maria's mom should choose the casserole dish with a volume of 4200 cm³ (Option B), as it is the only dish that is large enough to hold the entire 4000 cm³ casserole without overflowing.
Step-by-step explanation:
To determine which casserole dish Maria's mom should use for her sweet potato casserole, we must look at the volume of the casserole she wishes to make and the volumes of the available dishes. Maria's casserole has a volume of 4000 cm³. Three dishes are available with volumes of 3500 cm³, 4200 cm³, and 3900 cm³ respectively. The dish with a volume of 3500 cm³ is too small, and the dish with a volume of 3900 cm³ is still too small, although it is quite close to the required volume. Therefore, the only suitable dish is the one with a volume of 4200 cm³ (Option B), as it is the only one that can contain the entire casserole without overflow.
For related metric units of capacity, 4 liters is equivalent to 4,000 milliliters. When Devon from the catering company is preparing food for a party, she has to convert the total milliliters of soup needed for 100 guests into liters. If each guest gets 375 milliliters of soup, she will need 375 mL x 100, which equals 37,500 milliliters, and when converted to liters (35,000 mL ÷ 1,000 mL/L), this results in 37.5 liters of soup.
