Answer:
![V=144\ cm^3](https://tex.z-dn.net/?f=V%3D144%5C%20cm%5E3)
Step-by-step explanation:
#We use the base diagonal and the height diagonal to calculate the beam's height:
![h=\sqrt{13^2-(4^2+3^2)}\\\\h=12\ cm](https://tex.z-dn.net/?f=h%3D%5Csqrt%7B13%5E2-%284%5E2%2B3%5E2%29%7D%5C%5C%5C%5Ch%3D12%5C%20cm)
#The volume of the beam can then be calculated as:
![V=lwh\\\\=4\times 3\times 12\\\\=144\ cm^3](https://tex.z-dn.net/?f=V%3Dlwh%5C%5C%5C%5C%3D4%5Ctimes%203%5Ctimes%2012%5C%5C%5C%5C%3D144%5C%20cm%5E3)
Hence, the beam's volume is ![144\ cm^3](https://tex.z-dn.net/?f=144%5C%20cm%5E3)
Step-by-step explanation:
All the steps are in the pictures. If you have any questions let me know and I'll explain in simple terms :)
Another easy way to remember the area of a square is s*s, or side times side.
if one side is 6 centimeters, then the other 3 are also 6 because it's a square.
so you can either do 6*6 = 36
or 6^2 = 36
