Step-by-step explanation:

Lateral surface area of prism = 120

base perimeter × heiht = 120

3×(side)×height=120

(Perimeter of eq.△=3×side)

Side×height=1203=40.....(i)

Volume of prism =403–√

Area of base × height = 403–√

3√4(side)2×height=403–√

(side)2×height=403–√×43–√

=160......(ii)

Dividing (ii) by (i)

(side)2×heightside×height=16040

side=4cm
