Calculate the volume of one sweet. Calculate the volume of the jar and then divide the volume of the jar by the volume of a sweet.
Results obtained by multiplying the length and width and height of the internal volume of the bath tub bath tub.
Length times width times height (lwh) is a way to figure out volume. If you try to do it with water displacement, the wood will adorn the water and ruin the calculations.
If the density of the block is less than the density of water, then the block will float. Density of water is close to 1 gram per cubic centimeter. So measure the block and calculate its volume (Length x Width x Height). Use a scale to find the block's mass. Then divide mass/volume to calculate density. If you've measured in grams and centimeters, then the units will be g/cm³, then compare this to 1 g/cm³.
To calculate the volume of water in a semicircular trough, one should figure out the area of the cross section (the semicircle) first. Then, this number should be multiplied by the length of the trough.
