Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Volume of room is 18 ft³ or less.

So, we need to find the dimensions which can represent a refrigerator that Heather can buy.

A) 2 ft. wide x 2.5 ft. long x 3 ft. tall

Volume will be = 2 × 2.5 × 3 = 15 ft³

B) 2 ft. wide x 2.5 ft. long x 4.5 ft. tall

Volume will be 2 × 2.5 × 4.5 =22.5 ft³

C) 2.5 ft wide x 3 ft. long x 4 ft. tall

Volume will be 2.5 × 3 × 4 = 30 ft³

D) 2.5 ft. wide x 2 ft. long x 4 ft. tall

Volume will be 2.5 × 2 × 4 = 20 ft³

So, Volume of refrigerator must be less than Volume of room i.e. 18 ft³

So, Volume of refrigerator can be 2 ft. wide x 2.5 ft. long x 3 ft. tall.

Hence, Option 'A' is correct.
