Answer:

[tex]V=(\frac{13}{8})^{3}\ ft^{3}[/tex], [tex]SA=6(\frac{13}{8})^{2}\ ft^{2}[/tex]

Step-by-step explanation:

we know that

The volume of a cube is equal to

[tex]V=b^{3}[/tex]

The surface area of a cube is equal to

[tex]SA=6b^{2}[/tex]

where b is the length side of the cube

In this problem we have

[tex]b=1\frac{5}{8}\ ft[/tex]

Convert to an improper fraction

[tex]b=1\frac{5}{8}=\frac{1*8+5}{8}=\frac{13}{8}\ ft[/tex]

Part 1) Find the volume

substitute the value of b in the formula

[tex]V=(\frac{13}{8})^{3}\ ft^{3}[/tex]

Part 2) Find the Surface area

substitute the value of b in the formula

[tex]SA=6(\frac{13}{8})^{2}\ ft^{2}[/tex]

Answer:

V=(13/8)3ft3; SA=6⋅(13/8)2ft2
