Natasha wants to use the Fermi process to estimate the number of pennies that would fill a toy chest. As part of the process, she needs to estimate the volume of the toy chest. She figures the toy chest is about 50 in. long, 20 in. wide, and 20 in. tall.   Which estimate best approximates the volume of the toy chest? Responses 2×103 in³ 2 times 10 to the power of 3 end exponent, in³ 2×104 in³ 2 times 10 to the power of 4 end exponent, in³ 2×105 in³ 2 times 10 to the power of 5 end exponent, in³ 2×106 in³ 2 times 10 to the power of 6 end exponent, in³
