Question

PLS HELP! :/
Marisol is in a bathtub that is shaped like a rectangular prism, about 5 ft long, 2 ft wide, and 1 ft deep. She is drinking hot cocoa that is in a cylindrical mug about 3 in. wide and 4 in. tall. She wonders how many mugs of water it would take to fill her tub. Her reasoning, shown here, contains an error.

The bathtub has a volume of about 17,280 in³, or about 1×104 in³.
The mug has a volume of about 28 in³, or about 3×101 in³.
1×1043×101=13×103 , so about 333 mugs of water would fill the bathtub.

What is Marisol's error?

A.The value 17,280 should have been rounded to 2×104 .

B.The volume of the tub is not abut 17,280 in³.

C.The value 28 should have been rounded to 2×101

D.The volume of the mug is not 28 in³.
