Answer:
Step-by-step explanation:
Remove the brackets.
ac - bc = d
Add bc to both sides
ac = d + bc
Divide by a
![\dfrac{ac}{a}=\dfrac{d + ab}{a}](https://tex.z-dn.net/?f=%5Cdfrac%7Bac%7D%7Ba%7D%3D%5Cdfrac%7Bd%20%2B%20ab%7D%7Ba%7D)
The "a"s cancel and you are left with the answer.
Answer
Answer:
The volume is ![12000 in^3](https://tex.z-dn.net/?f=12000%20in%5E3)
Step-by-step explanation:
From the question ,
and ![H=10\:in.](https://tex.z-dn.net/?f=H%3D10%5C%3Ain.)
The volume of a pyramid is given as
![V=\frac{1}{3} \times area\:of\:the\:base \times height](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%20area%5C%3Aof%5C%3Athe%5C%3Abase%20%5Ctimes%20height)
From the question, the base of the pyramid is a square.
Hence base area is given by ![L^{2}](https://tex.z-dn.net/?f=L%5E%7B2%7D)
This implies that the volume of the pyramid is
![=\frac{1}{3} \times L^{2}\times H](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%20L%5E%7B2%7D%5Ctimes%20H)
![=\frac{1}{3}\times 60^{2} \times 10](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B3%7D%5Ctimes%2060%5E%7B2%7D%20%5Ctimes%2010)
![=\frac{36000}{3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B36000%7D%7B3%7D)
![=12000 in^3](https://tex.z-dn.net/?f=%3D12000%20in%5E3)
I just copied and pasted your question on google and a graph came up it may not be the answer but i tried...
