What is the surface area of a rectangular prism with the following dimensions? length: 8 cm width: 13 cm height: 10.5 cm 63 cm2 1,092 cm2 2,184 cm2 649 cm2

Your answer would be 649cm2 given the dimensions

The solution: A=2(wl+hl+hw)=2·(13·8+10.5·8+10.5·13)=649cm²

Option D. 649 cm² is the correct option.

Step-by-step explanation:

Since surface area of a rectangular prism is calculated by the formula

Surface area = 2(length×width + width×height + length×height)

= 2(8×13 + 13×10.5 + 8×10.5)

= 2(104 + 136.5 + 84)

= 2(324.5)

= 649 cm²

Therefore, Option D. 649 cm² is the correct option.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
