Question

A right prism has lateral edges of length 10cm and bases that are equilateral triangles with sides of length 8 cm

a. find the total area
b. find the volume

Answer 1

b) the total volume is
Prism Volume = Area of Base * Height
Prism Volume = 27.713 * 10
Prism Volume = 277.13

a) the total area is
Surface Area = Lateral area + Area of two ends

Lateral Area = 10 * 8 * 3 sides = 240
area of both ends = 27.713 * 2 = 55.426

Total Area = 240.00 + 55.426 = 295.426
