The volume of number three is 63.7
Lets first convert everything to inches.
6 feet= 12*6 = 72 + 10 = 82 inches
8 feet= 12*8 = 96+9 = 105 inches
Now add!
82+105 = 187
Now convert them back to feet.
187/12 = 15 feet
12*15 = 180
187 - 180 = 7 inches
15 feet. 7 inches.
Final answer: B. 15 ft. 7 in.
Well, 50 x 4 = 200, so just keep adding 0's!
50 x 4= 200
50 x 40 = 2,000
50 x 400 = 20,000
500 x 400 = 200,000
