We have: 5m 75cm = 5.75 m
So the length of each piece is : ![l = \frac{5.75}{5} =1.15](https://tex.z-dn.net/?f=l%20%3D%20%5Cfrac%7B5.75%7D%7B5%7D%20%3D1.15%3Cm%3E)
ok done. Thank to me :>
Step-by-step explanation:
the volume of a cube is
side³.
since the volume is 27 m³, the individual side lengths are then the cubic root of 27 = 3 m.
the surface area is 6 squares of 3×3 = 9m², so in total
9 × 6 = 54 m²
The answer is step 3. Step 2 is suppose to be 3 x 7 and the answer is 21 but he writes 7 in step 4
