It is: 4*3*2 = 24 cubic cm
Surface area = 2*(12*8 + 8*9 + 9*12) sq cm = 2*(96 + 72 + 108) = 552 cm2

Let the length be x:- 2*(x+79) = 350 2x+158 = 350 2x = 350-158 2x = 192 x = 96 centimeters Check: 96+96+79+79 = 350 centimeters
2 centimeters is just 2 centimeters, and 2 centimeters squared is 4 centimeters. 2 centimeters x 2 centimeters = 4 centimeters squared = times 2
It is: 4*3*2 = 24 cubic cm
Assuming your dimensions must be whole numbers! 1 x 8 x 50; 2 x 8 x 25; 5 x 8 x 10

Assuming this is a rectangular prism, the volume is height*width*length = 2(cm)*3(cm)*6(cm)= 36 cm3
Surface area = 2*(12*8 + 8*9 + 9*12) sq cm = 2*(96 + 72 + 108) = 552 cm2

The good thing about the developments of rectangular boxes is that they are still rectangular! In order to find the surface area of the paper needed to make a box, you would first need to determine the measurements of your finished box. One you have determined your length (L), width (W), and height (H), you will need to do some simple math. 2(LxW) + 2(WxH) + 2(LxH) = the area of paper that you need to make a box.
The surface area = (18 cm x 20 cm) + 4(10 cm x 20 cm) = 360cm^2 + 800 cm^2 = 1,160 cm^2
