Question

Hannah wants to find the volume of a rectangular wooden block. She correctly measures the length of the block to be 7 cm and the width of the block to be 1 cm, but while measuring the height of the block, she makes a mistake and incorrectly measures it to be 2 cm. The actual height of the block is 3 cm.

If Hannah uses the following equation to calculate the volume of the block

7 cm X 1 cm X 2 cm = 14 cm2
Hannah's calculated volume

will have different units than the actual volume of the block.

will be higher than the actual volume of the block.

will be lower than the actual volume of the block.

will be exactly the same as the actual volume of the block.

Answer 1

This --> 7 cm X 1 cm X 2 cm = 14 cm2 is supposed to be cubic centimeters.

Is that a typo or is it how the problem is written?

Answer 2

its how the problem is written

Answer 3

it is c, because 14 cm is less than 7X1X3=21cm cube

Answer 4

as for that, it guess it is a typo

Answer 5

i believe so

Answer 6

This looks like a viable option to me: will have different units than the actual volume of the block.

Answer 7

14 cm2 is not a measure of volume. So, how can it be compared to 21 cubic cm.
It's one of those apples and oranges things.
