Solve the problem.Amy is making a cubic cardboard box and intends it to be 10 in. long on each side. She can't find her ruler, so the errors in her measurements can be up to 10%. Express the possible volume of the box V as an inequality and graph the values of V.
V = volume in cu. in.
A. 900 ? V ? 1100 V = volume in cu. in.
B. 1000 ? V ? 1331 V = volume in cu. in.
C. 1000 ? V ? 1100 V = volume in cu. in.
D. 729 ? V ? 1331 V = volume in cu. in.
