SA=2(lw) + 2(lh) + 2(wh)
=2(6x8)+2(6x5)+2(8x5)
=2x48+2x30+2x40
=96+60+80

Find the surface area of the rectangular prism 6cm , 6cm , 12cm
The base is a square, so since it's area is 25 cm2 it's sides are 5 cm each in length. Thus, the rectangular sides of the prism have an area of 5x12 or 60 cm2. The total surface area is the sum of the 4 rectangular sides at 60 cm2 and the two square faces at 25 cm2.4*60 + 2*25 = 240 + 50 = 290 cm2
32 cm2 x 7 cm = 224 cm3.
Volume of a rectangular prism = length * width * height = 16cm*10cm*5cm = 800cm3
11.625cm2 divide 186 by 1.6 and you'll get 116.25
First you find the area of the surface and then you multiply that by the height of the prism. Example if the surface area is 6cm and the height is 5cm then the volume is 6 time 5 cm cubed. So 30cm Cubed. All volume is measured in cubic cm or m . Cool.
the awnser is 552 ok :)

You need more than one measurement.
112 cm squared
2 cm
2 cm
20 cm * 11 cm * 12 unspecified units will have a surface area of 440 cm2 + 744 cm*unspecified units.
You need three measures of length to determine the surface area - the length, width and height.
Assuming you mean a rectangular prism, you get the smallest surface area if the prism is a cube. You can calculate the required length of side to get that volume; then, based on that, the corresponding surface area.
174m2 :) i had the same question on a test :)
It is 2*(7*4 + 4*2 + 2*7) = 100 square cm.
