Bob’s aquarium can hold more.
The formula for volume is Length x Width x Hight. Using that formula you get 1680cm2 for Terry’s and 2925cm2 for Bob’s.
If the ones digit is "d", the number is (d+4)(2(d+4))(d), and the sum of digits is 4d+12 = 12. Then d=0.
The number is 480.
The solution and the answer are in the photograph.
The whole second is the first number to the left of the decimal (_.), so : 35.78=36 because 7>5. 39.51=40 because 5=5. 40-36=4. Bailey won the race by about 4 seconds. Hoped I helped!
