Question

HELP , not sure what to do…….

Answer 1

Step 1 Identify the dimensions and their values.
The length of the rectangular prism is 6cm. The width is 2cm and the height is 3cm.
- Okay I get this part….

Step 2 Plug the values into the equation.
S = 2lw + 2lh + 2wh
S = 2(6cm)(2cm) + 2(6cm)(3cm) + 2(2cm)(3cm)
S = 160in2 + 240in2 + 192in2 S = 592in2
S = 2(12cm2) + 2(18cm2) + 2(6cm2)
S = 24cm2 + 36cm2 + 12cm2
S = 72cm2
- This is where I get lost. When the numbers are plugged in , I’m not sure how 2(6cm)(2cm) turns into 160in2 do they multiply or what ???

Answer 2

the dimensions are 12, 8, 10. that's the length, width, height.
idk where 6,2,3 are coming from...
is this the full question?

Answer 3

Sorry i attached the wrong image..

Answer 4

haha... now that makes more sense.

Answer 5

Yeaaah lol .-.

Answer 6

so this 3rd line you have up there is not supposed to be there:
S = 160in2 + 240in2 + 192in2 S = 592in2

eliminate this ^^

Answer 7

so now what you have for S is your surface area of the rectangular prism

Answer 8

Ohhhhhh , okay thankyou (:
