Answer:
TSA of 1 cube = 6a²
= 6 X 1²
= 6 X 1
= 6cm
total no. of cubes = 3
= 6 X 3
= 18cm
therefore, the TSA of the all cubes = 18cm
volume of cube= a³
= 1³ = 1cm
total no. of cubes = 3
= 3x1 = 3cm
therefore, the volume of all cubes = 3 cm
Volume of the cuboid formed = L × b × h
= 1cm × 1cm × 1cm
= 1cm
