we have a triangular prism

the surface area will be the total area of all the sidesand all the faces,

we have 2 triangles

and 3 rectangles

if we can "open"our prism

A=1/2 b*h is to find the triangle area

the height is 16-10=6

A triangle= 1/2*13*6=13*3=39 cm^2

we can use the formula

I will useA= b*h+L(s1+s2+s3)

where b=13 cm

h=16 cm
