Question

I never help quick! A kaleidoscope is made of stained glass in the shape of a triangular prism. The bases are equilateral triangles. Find the surface area of the kaleidoscope​

Answer 1

• 46.8 in²

Explanation:

Total surface area comprises of two bases and 3 faces:

• S = 2(1/2*1.5*1.2) + 3(1.5*10) = 46.8 in²

Answer 2

Solution given:

length=10in

again

base=2√{1.5²-1.3²)=1.49

Total surface area =lateral surface area +2 curved surface area

=perimeter of triangle ×length +2×1/2 base×height

=(1.49+1.5+1.5)×10+1.3×1.49=46.837in²
