Step-by-step explanation:

From the question we are told that  

   The lateral edge of a square prism is  

    The angle of inclination is  

    The volume of the prism is  

Generally the base of the prism is mathematically represented as

=>  

=>  

Generally the lateral  area of the prism is mathematically represented as

=>    

=>    

Generally the total area of the prism is mathematically represented as

=>  

=>  

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
