Could someone help me with this? Could you also give a step by step explanation? ;-;

ok for this we have to multiple the sides of the presents

10.5*16=168

34*23=782

7*7=49

now we add then together

49+782+168=999

so the stuff covers a area of 999 square cm

please give brainlest since this took a while

1272 cm

Step-by-step explanation:

Multiply: 10.5*16=168

34*23=782

7*7=49

21*13=273

Add: 168+782+49+273=1272

Plug in units: 1272 cm

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
