Answer:

AB = 3.5 cm

Explanation:

The volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular face and h the length of prism )

Here V = 84 and h = 12 , thus

12A = 84 ( divide both sides by 12 )

A = 7 ← area of Δ ABC

Thus


(1)/(2) × 4 × AB = 7

2AB = 7 ( divide both sides by 2 )

AB = 3.5 cm
