Surface Area - Cuboid

         

In the diagram above shows a cuboid with x=6,y=3,x=6, y=3, and z=4.z=4. Find the surface area of the cuboid.

Note: The above figure is not drawn to scale.

The above diagram shows a large cuboid with a smaller cuboid cut off from the corner. If α=6,β=3,\alpha=6, \beta=3, γ=6,\gamma=6, x=11,y=6,x=11, y=6, and z=12,z=12, what is the surface area of the remaining body?

Note: The above figure is not drawn to scale.

The cuboid in the above diagram is to be tiled by square-shaped tiles on all six faces of the cuboid. If x=10x=10 cm, y=4y=4 cm, z=4z=4 cm, and the side length of each tile is 22 cm, how many tiles are needed?

Note: A tiling is a non-overlapping arrangement of tiles covering the entire surface area with no gaps. The above figure is not drawn to scale.

What is the surface area of a cube inscribed in a sphere with radius 6,6, as shown in the above diagram?

The volume of the cuboid shown in the above diagram is 56.56. If x=7x=7 and y=2,y=2, what is the surface area of the cuboid?

Note: The above figure is not drawn to scale.
