I wonder if it is a proof question, because it is a formal way to prove the volume formula.
But otherwise, it is really straight forward, it even said it in the question: It's 7m by 8m by 4m. whatever that gives.
As a non verbal convention, when we describe a geometric shape, we describe it's dimensions "by" each other. In particular 2D shapes we say "base by height" which is exactly it's area (and a factor). Similarly for 3D we say "length by height by width" which is measurment of its volume (with a factor). The only thing tricky would be recognize the shape and determine what that "factor" is.
If you want a functional proof of the formula, message me.
volume = height x area_base = 4.5m x (7m x 2.6m) = 81.9 m3
70m3
-5(7m + 9) -7m
7m-5 = 9 7m = 9+5 7m = 14 m = 2
7m = 700cm, so 732cm is longer than 7m.
volume = height x area_base = 4.5m x (7m x 2.6m) = 81.9 m3
7*8*4 = 224 cubic metres.
The volume is 461.81 cubic meters.
If that is in water, 7m l
A triangle doesn't have volume.
85x7x4=2380 cubic meters
70m3
Volume = 1/3*pi*72*15 = 245pi cubic m

To prepare 7M sulfuric acid from concentrated sulfuric acid, first calculate the volume of concentrated sulfuric acid needed to make 7M solution. Then, measure the calculated volume of concentrated sulfuric acid and carefully dilute it with water to the desired volume while stirring continuously. Make sure to add acid to water slowly to prevent splashing or generation of heat.
-5(7m + 9) -7m
A cylinder with a diameter of 7 meters and a height of 12 meters has a volume of 461.81 cubic meters.
