Question

the total surface area of a cube is 294cm^2 work out the volume of the cube

Answer 1

Answer:

total surface area=6x^2

area=x^3

6x^2=294

x^2=294/6

x^2=49

x=SQR(49)

x=7

x^3=7^3

area=343

Answer 2

Good morning,

Answer:

343cm³

____________________

Step-by-step explanation:

total surface = 6r² ⇔ 294=6r²

Then, r²=294÷6=49

Then r=√(49)=7

Therefore the volume = r³=7^(3)=343cm³.
