Density = Mass/Volume = 850/(9*7*12) = 1.1243 grams per cm3
32 x 12 = 384 cm3
A rectangular prism of 10 by 8 by 12 will have a volume of 960 cubic cm
Rectangular prism is an example of a cuboid and surface area of a cuboid is given by: S = 2x(l+b+h) We can say l = 20cm, b = 11cm & h = 12cm So, surface area of the rectangular prism = 2x(20+11+12)cm2 = 2x43cm2 = 86cm2
5cm by 7cm by 12cm
2*5*12 = 120 cm3
SA=2(lw) + 2(lh) + 2(wh) =2(6x8)+2(6x5)+2(8x5) =2x48+2x30+2x40 =96+60+80 =196cm2
264/22=12 Therefore, the height is 12cm
30cm
The formula for the surface area is 2lw + 2hl +2hw. So, 2(9*12)+2(9*12) +2(9*9)=?
The equation for the density of an object with known mass m and volume V is D=m/V.You are given the mass to be 750g.To figure out the volume of the block of wood, simply multipy all of the dimensions. The volume of a right prism (e.g. a block of wood) is V=length*width*height, so the volume for the block of wood is 12cm*8cm*9cm=864cm3.Now you know both your mass and your volume, so you can calculate the density:D=m/VD=(750g) / (864cm3)D is roughly equal to 0.86806g/cm3.
To calculate the volume, multiply the length x width x height. volume = 12cm x 6cm x 4cm = 288cm3
