I believe that your asking for two answers. The volume of the pyramid is 15 cubic centimeters and If the slant increases by 4 centimeters and its hheight increases by 2 centimeters the volume increases by 6 centimeters because the answer would be 21. 21-15=6. Formula to get the volume of a pyramid is V=1/3*(L*W)*H. I could be wrong.
Answer:
No her calculations do not make sense because the area of the smaller walls together is 234 and not 244 the total square feet of the windows and doors are also wrong. She should also subtract the doors and windows from the total so she doesn't over spend on paint. Her answer is correct just the way of finding it is wrong.
Step-by-step explanation:
Walls total sqft: (2(13ft)(9ft))+(2(16ft)(9ft))=234ft²+288ft²=522ft²
Doors+Windows total sqft: ((2(20ft)+(2(15ft))=60ft²+30ft²=90ft²
Total amount of paint needed: 522ft²-90ft²=432ft²
Amount of gallons needed remains the same
Hopefully this makes sense.
It will cost Bradley $7,500 for him to cover up his T.V. screen. Honestly, I don't think that he should cover up his T.V. screen because it is useless and a waste of money.
