Answer:
volume of cuboid=60 cm^3
Step-by-step explanation:
given:
surface area of cuboid(SA)= 94 cm^2
breadth(b)=4 cm
height(h)=3 cm
using formula of surface area of cuboid=2(lb+bh+hl)
SA=2(l*4+4*3+3*l)
94=2(4l+12+3l)
94/2=4l+3l+12
47=7l+12
47-12=7l
35=7l
35/7=l
l=5 cm
volume of cuboid(v)=l*b*h
V=5*4*3
volume of cuboid =60 cm ^3
