7.Volume of each cube = edge x edge x edge = 3 x 3 x 3 cm2 = 27 cm3 Number of cubes in the surface structure = 15 Volume of the structure = 27 x 15 cm3 405

8.We know that volume of cuboid = | * b*h

We know that volume of cube = a^3

volume of cuboid = volume of cube

9 8h = 6^3

72h -216

h 3 cm.
