Answer:
Therefore the team saves $5.18.
Step-by-step explanation:
i) there are two triangular pyramids
ii) the base of each pyramid is an equilateral triangle with an area of 10.8 square feet.
iii) the base of the pyramids are not covered with foil.
iv) since there are two pyramids the total area not covered
= 10.8 [tex]\times[/tex] 2 = 21.6 square feet
v) the cost of foil = $0.24 per square foot.
vi) the team save altogether by covering only the lateral area of the two pyramids
= 21.6 [tex]\times[/tex] 0.24 = $5.18
Therefore the team saves $5.18.
