What is the density of a cube that weighs 1.35g and has sides 14.3cm in length?

Volume of the cube = (14.3 cm)3 = 2,924.207 cm3
Density = 1.35 / 2924.207 = 0.000462 gm/cm3
(This is about 2.6 times the density of helium at
standard temperature and pressure.)
Note:
Density is computed by mass and volume, not weight and volume.
We've assumed that the '1.35g' quoted in the question is mass, not
weight, even though "gram" is so often erroneously used as a unit
of weight.

What Has all sides are equal in length and measure?
A square! The sides are all the same length and measure.
What type of triangle has two sides the same length?
If only two sides of a triangle are the same length it is an isosceles triangle. If all three sides are the same length it is an equilateral triangle.
Classification of triangle according to sides?
A triangle in which all sides are of equal length is an equilateral triangle.A triangle in which two sides are of equal length is an isoceles triangle.A triangle in which all sides are of different length is a scalene triangle.
What is the difference between an isosceles trapezoid and an isosceles triangle?
An Isosceles trapezoid has four sides (is a quadrilateral) with a pair of parallel sides and the other two sides of equal length; whereas An isosceles triangle has three sides with a pair of sides of the same length and the other side a different length.
What is the length of each side of a 100.0 gram cube of platinum that has a density of21.45 g?
Density cannot be measure in g. Consequently, the question does make sense. If the density is 21.45 gcm-3, then the volume is Mass/Density = 100/21.45 = 4.6620 cm3. Then the length of the cube's sides are (4.6620)1/3 cm = 1.671 cm.
How do you determine area if given density mass and length?
How do you determine area if given density mass and length?Density = Mass ÷ volumeVolume = L * W * HtArea = L * WVolume = Area * HtDensity = Mass ÷ volumeDensity = Mass ÷ (Area * Ht)Multiply both sides by AreaArea * Density = Mass ÷ HtDivide both sides by DensityArea = Mass ÷ (Ht * Density)
What is the term for sides with the same length?
Sides with the same length are congruent.

Does a trapezium have all sides the same length?
no. one of the sides is a different length.
Do hexagon have two sides equal length and two sides different length?
Hexagons have six sides, not four. Any number of them can be of the same length.
What are some attributes of a rectangular prism?
It has 6 sides, 8 corners, 12 edges, a height, length and width. It may also have a color or density or weight.
What shape have 10 sides but the sides are different length?
A polygon with 10 sides is called a decagon. the length of the sides doesn't matter, as long as it has ten sides.
What are isosceles and scalene triangles?
isosceles - 2 sides of the triangle are the same length scalene - no sides are the same length equilateral- all sides are the same length
