i am looking for some help!
I need to figure out the surface area of a 2cm cube, with dimensions length, width and height all 2cm. My answer is 0.0012 m squared... Is this right? I have no idea!
A 4cm cube with length, height and width all 4cm. My answer is, surface area= 0.0024 m squared. Again not sure if I'm on the right track...
A rectangular prism with length 4cm, width 3cm and height 6cm. My answer is, surface area= 24 millimetres which just doesn't seem right.
A rectangular prism with length 12cm, width 9cm and height 6cm. My answer is, surface area= 648 millimetres. Again doesn't seem right!
And then theres the cylinders...
I need to find the surface area of two. The first has a radius of 1cm and a height of 3cm. The second has a radius of 4cm and a height of 12cm.
If you can provide me with any tips on how to find volume too, I would be very grateful. All basic stuff I know, but I just can't figure this stuff out!
Thanks in advance
