4 x 5 x 2 = 40cm3
We know that density=mass/volume so the density of the cube= 16 g (the mass)/64 cubic cm= 0.25 g/cubic cm
96 cm.^2
The formula for the volume of a cube is height x width x length, therefore V = 4cm x 4cm x 4cm V = 64cm3
The circumference of a circle with a radius of 4cm is: 25.13 cm (r x 2 x pi)
24 cm3
The volume of the cube is 4cm x 4cm x 4cm = 64 cm^3. To find the density, divide the mass (50g) by the volume (64 cm^3): density = 50g / 64 cm^3 ≈ 0.78 g/cm^3.
4 x 5 x 2 = 40cm3
We know that density=mass/volume so the density of the cube= 16 g (the mass)/64 cubic cm= 0.25 g/cubic cm
Volume of a cube (or cuboid) is length x width x height. In the case of a cube, all three are the same: length = width = height. For a 4cm cube, length = width = height = 4cm, thus: volume = 4cm x 4cm x 4cm = 64cm3.
96 cm.^2
The formula for the volume of a cube is height x width x length, therefore V = 4cm x 4cm x 4cm V = 64cm3
Density=Mass/Volume Mass=19.2 grams Volume=4cm x 3cm x 2cm=24 cm^3 Density=(19.2 grams)/(24 cm^3)= 0.8 g/cm^3 Note the unit, grams per cm^3, which is the mass unit divided by the volume unit.
6 cm x 4 cm = 24cm2 (length x width = area)
The circumference of a circle with a radius of 4cm is: 25.13 cm (r x 2 x pi)
4 X 4 X 4 = 1936 square cm
V = 4/3 (3.14) (4cm x 4cm x 4cm) V = 803.84 cm3 / 3 V = 267. 95 cm3
