1.4 A?

OpenStudy (masterdestroyer55):

length × width × height = 6×3×5

OpenStudy (masterdestroyer55):

90m3

OpenStudy (masterdestroyer55):

surface area = 2(3×5)+2(6×5)+2(3×6)

OpenStudy (masterdestroyer55):

2(15)+2(30)+2(18)

OpenStudy (masterdestroyer55):

30+60+36 = 126

OpenStudy (mathstudent55):

Your volume and area are both correct.

OpenStudy (mathstudent55):

Your final answer is correct.

OpenStudy (masterdestroyer55):

126 : 90 126/90 = 1.4 so it is A?

OpenStudy (mathstudent55):

Yes.
