That's the area.
The prism is a three dimensional object. 3-D objects do not just have area. They have something call surface area, which is the amount of around on the surface of the object. 3-D objects also have volume. Volume is the amount of space inside the object. You can not work out the surface area of volume of just a prism. There are many many prisms out there. Prisms have many shapes and sizes.
Now that depends on if you mean outside surface area. A cone has an inside surface area too. Just adding my two cents. Not even good at math. But I can debate a point til the death!

The lifting power of a helium balloon depends on its size and the amount of helium inside. On average, a standard 12-inch helium balloon can lift about 14 grams.
Yes.
The balloon can pull the can up until the weight of the water inside the can is equal to the buoyant force acting on the balloon. This depends on the size of the balloon and the amount of air it contains. Adding more water will increase the weight inside the can, making it difficult for the balloon to lift it.
The amount of force exerted on a balloon by the gas inside is called the internal pressure. This pressure is caused by the gas molecules colliding with the walls of the balloon. The greater the number of collisions, the greater the force exerted on the balloon.
Pressure inside of a balloon is created by the movement of the air molecules against the inner surface of the balloon. The more air inside the balloon, the more molecules that are hitting the same surface are, so there is more pressure.
When air is blown into a balloon, it fills the space inside. The pressure of the air increases, causing the balloon to expand. If the balloon is sealed, the air inside remains trapped, making the balloon float or hover depending on the amount of air inside.
The pressure inside a balloon is determined by factors such as the amount of air or gas in the balloon, the volume of the balloon, and the temperature of the air or gas inside. As more air or gas is added to the balloon, the pressure will increase. Conversely, if air or gas is released from the balloon, the pressure will decrease.
Yes it does, it also depends on how big the are inside the balloon is too. because think of a chinese lantern, as this floats to the sky using the hot gas from the fire, now think of a hot air balloon in the same way :)
