Which could be the area of the base of the triangular prism?

[Not drawn to scale)

• 6 ft²

• 10 ft²

• 12 ft²

• 20 ft²

Answer:

6ft²

Step-by-step explanation:

The formula for the base area of a triangular prism is given as:

Area of the base = √s(s-a) (s-b) (s-c)

Where s = (a+b+c)/2

From the attached diagram,

a = 5ft

b = 3ft

c = 4ft

s= (5ft + 3ft + 4ft) ÷ 2

s = 6ft

Area of the base = √ 6( 6-5) (6-3) (6-4)

= √6(1)(3)(2)

= √36

= 6ft²

Therefore, the area of the base of the triangular prism is 6ft²

I think the best figure for a cereal box would be a cylinder. There are no corners on a cylinder where it is hard to fit round pieces of cereal into. The formula for the surface area of the cylinder is 2*pi*r*h+2*pi*r^2. The formula for the volume of the cylinder is pi*r^2*h. (Then I would add some more info supporting why you think a cylinder would make a good box.)
