What is the surface area?

1 answer:

4 0

The formula for the surface area of a rectangular prism is

A= 2(wl+hl+hw)

We are given the height =2cm, width= 5cm, and length= 10cm. All you have to do is plug this info in!

A= 2(wl+hl+hw)
= 2[(5)(10)+(2)(10)+(2)(5)]
= 2(50+20+10)
= 2(80)
=160 cm squared

Hope this helps!! :)

What will the coordinate K(3, - 3) be after the translation 8 units to the left and 7 units up.

Answer:

(-5, 4)

Step-by-step explanation:

To find the new coordinate, subtract 8 from the x value and add 7 to the y value:

3 - 8 = -5

-5 will be the new x coordinate

-3 + 7 = 4

4 will be the new y coordinate

So, the coordinate K will be (-5, 4) after the translation
