Whoever helps i will give the brainliest! What is the total amount of edging that would be required to cover all edges of a rectangular prism measuring 10 cm by 15 cm by 30 cm??

220 cm total of edging

Step-by-step explanation:

you would have 4 edges of each length.

4 x 10 = 40

4 x 15 = 60

4 x 30 = 120

40 + 60 + 120 = 220 cm

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
