Find the surface area of an open box with length of 12 inches, width of 7 inches, and height of 4.5 inches

339 inches ²

Step-by-step explanation:

First, the formula of a rectangular prism is...

2(wh+lw+lh)

*witch means 2(with x height + length x with + length x height)*

So, the equation would be...

2×(12×7 + 12×4.5 + 7×4.5)

Which answers to 339.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

40 is the final : )
