What is the surface area of this triangular prism

The surface area of this prism consists of:

Sprism = Sprism + Ssides

the bases of triangles the area of each one is

Atriangle = 1/2bh

Aonebases = 1/2bh

Abothbases = 2×1/2×bh = bh

Arectangle = l×w where l is the length and w is the width

Aside = ls

If the triangular base has unequal sides then you calculate the perimeter( P) of the triangle and multiply it by the height of the prism to get the area of the sides (lateral surface area)

If the base is an equilateral triangle then all three sides have equal areas and the lateral surface area becomes = 3ls

Sprism = bh+pl
