Answer:
160cm²
Step-by-step explanation:
To find the area of cuboid made by joining 2 cubes of side 4cn each, first you have to join the both figures of 2 cubes
then, there will be new dimensions ,
length=4cm
breadth=4+4=8cm
height=4cm
therefore as you have studied you can find the area of a cuboid pretty easily
l=length
b=breadth
h=height
surface area=2lb+2lh+2hb
=(2×4×8)+(2×4×4)+(2×8×4)
=64+32+64
=160cm²
