If the two ends of this triangular right prism are equilateral triangles. The surface area of the prism is 74cm.
<h3>Surface area</h3>
Using this formula
A=bh+L(S1+S2+S3)
Where:
L=5cm
b=4cm
h=3.5cm
S1=4cm
S2=4cm
S3=4cm
Let plug in the formula
A=4(3.5)+5(4+4+4)
A=14+5(12)
A=14+60
A=74 cm
Therefore the surface area of the prism is 74cm.
