A 0.0979-m x 0.215-m x 0.260-m block is suspended from a wire and is completely under water. What buoyant force acts on the block?

Would I multiply all the numbers?

Yes, for the volume of the block, but you also have to multiply by the weight density of the fluid, which is

1000 kg/m^3 * 9.8 m/s^2 = 9800 N/m^3

Your answer must be in newtons, not cubic meters

To calculate the buoyant force acting on the block, you need to use the formula:

Buoyant force = weight of the fluid displaced

To find the weight of the fluid displaced, you need to know the density of the fluid and the volume of the block.

The density of water is about 1000 kg/m^3.

Since the block is completely submerged in water, the volume of the block is equal to the volume of the fluid it displaces.

To find the volume of the block, you multiply its dimensions together:

Volume = 0.0979 m x 0.215 m x 0.260 m

Now that you have the volume of the block, you can calculate the buoyant force:

Buoyant force = density of fluid x volume of block x acceleration due to gravity

Therefore, the buoyant force acting on the block will be the product of the density of water (1000 kg/m^3), the volume of the block (0.0979 m x 0.215 m x 0.260 m), and the acceleration due to gravity (9.8 m/s^2).

To calculate the buoyant force acting on the block, you need to know the density of the fluid in which the block is submerged. Let's assume that the fluid is water, which has a density of approximately 1000 kg/m^3.

The buoyant force can be calculated using the formula:
Buoyant Force = Volume of the displaced fluid x Density of the fluid x Acceleration due to gravity

To find the volume of the displaced fluid, you need to calculate the volume of the block. In this case, the volume is given as:
Volume = Length x Width x Height

So, you can multiply the given dimensions of the block (0.0979 m x 0.215 m x 0.260 m) to find its volume.

Then, multiply the calculated volume by the density of water (1000 kg/m^3) and the acceleration due to gravity (9.8 m/s^2). This will give you the magnitude of the buoyant force acting on the block.
