Answer:
364 cm or 368 cm
Explanation:
top of pink cuboid is 2 x 2 which is 4
sides of pink cuboid are 6 x 6 and there are 4 of the same faces so 6 x 6 x 4
green cuboid side is 5 x 4 and there are 2 faces that are similar so 5 x 4 x 2
the other side of the green cuboid is 10 x 4 and there are 2 faces that are similar so 10 x 4 x 2
the bottom and top would be 10 x 5 and there are 2 faces that are similar so 10 x 5 x 2 but a chunk of the top face is being blocked so we have to subtract the amount thats blocking it off so we do( 10 x 5 x 2 ) - ( 2 x 2 ), 2 x 2 is the face blocking it off.
the total then adds up to 364 cm but if that doesnt work then do 364 because it might be trying to count in bottom face of the pink shape
