The following is the formula for volume:
[tex] V=lwh [/tex]
The easiest way to solve this problem would be to plug in each answer. Let's try them all.
A.) [tex] (15cm)(2cm)(7cm)=210cm^3[/tex]
B.) [tex] (14cm)(3cm)(7cm)=294cm^3[/tex]
C.) [tex] (7cm)(3cm)(10cm)=210cm^3 [/tex]
We can eliminate B since it does not equal 210 cubic centimeters [tex](cm^3)[/tex]. By the way, the reason we get cubic centimeters [tex](cm^3)[/tex], is because we multiply cm*cm*cm.
Your answers would be A and C, since they both equal [tex]210cm^3[/tex].
