what is the length of the diagonal for the given rectangular prism to the nearest whole unit if the length is 8cm, width 3cm, and height is 7cm

168cm

Step-by-step explanation:

Length: 8cm

Width: 3cm

Height: 7cm

I divided 8 and 7 first and got 56.

Next I multiplied 56 and 3 and got 168.

So the length is 168cm

(Hope this helped! <3)

(sorrry if its wrong I feel stupid today)

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
