Base of a cube is a square, and in the given figure it's stated that the measure of each side is " x " ft

Therefore it's Area is equal to : -

  • side \times side

  • x \times x

  • {x}^{2}

Now, since it's Area is given as 1/4 ft², let's equate the Areas to find the measure of each side ~

that is ~

  • {x}^{2}  =  \dfrac{1}{4}

  • x =  \sqrt{ \dfrac{1}{2}  \times  \dfrac{1}{2} }

  • x =  \dfrac{1}{2}  \:  \: feet

It's time to find the volume of cube that is ~

  • (side) {}^{3}

So, let's plug the value of side length (1/2 ft)

Volume is equal to ~

  • {  \bigg(\dfrac{1}{2} \bigg) }^{3}

  • \dfrac{1}{8}  \:  \: ft {}^{3}

Hence, the required 1/8 or 0.125 ft³

I hope it helped ~
