If the prize table takes a break every 20 minutes it should eventually get a break in an hour
The refreshment table get a break every 30 minutes so it will take a second break in an hour
At 60 minutes they will be able to have a break together
The correct option is Option 4: ![2a^2b^3 + 10ab^4](https://tex.z-dn.net/?f=2a%5E2b%5E3%20%2B%2010ab%5E4)
Step-by-step explanation:
Given
Length of box = l = ab
Width of box = w = a+5b
Height of box = h = 2b^2
The volume of a box is given by:
![V = Length*Width*Height\\V = l*w*h](https://tex.z-dn.net/?f=V%20%3D%20Length%2AWidth%2AHeight%5C%5CV%20%3D%20l%2Aw%2Ah)
Putting the values
![V = (ab)(a+5b)(2b^2)\\ = (ab)(2b^2)(a+5b)\\=(2ab^3)(a+5b)\\Distributive property\\=(2ab^3*a) + (2ab^3*5b)\\=2a^2b^3 + 10ab^4](https://tex.z-dn.net/?f=V%20%3D%20%28ab%29%28a%2B5b%29%282b%5E2%29%5C%5C%20%3D%20%28ab%29%282b%5E2%29%28a%2B5b%29%5C%5C%3D%282ab%5E3%29%28a%2B5b%29%5C%5CDistributive%20property%5C%5C%3D%282ab%5E3%2Aa%29%20%2B%20%282ab%5E3%2A5b%29%5C%5C%3D2a%5E2b%5E3%20%2B%2010ab%5E4)
Hence,
The correct option is Option 4: ![2a^2b^3 + 10ab^4](https://tex.z-dn.net/?f=2a%5E2b%5E3%20%2B%2010ab%5E4)
