Answer 1

Answer:

How many cubes are joined end to end ?

We need the number of cubes joined to find out the surface area of the resulting cuboid !

The formula becomes

Surface area of cuboid = l × b × h

Here l and b and h can only be determined by having the value of no. Of cubes taken !!

Hope you understand, mate :)

Take Care✌✌❤

After joining the cubes a cuboid will be formed of dimensions

4×8×4

Hence, Surface Area of Cuboid is =2(4×8)+2(8×4)+2(4×4)=160 cm 2
