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

What is the length of each side of a square that has the same area as a rectangle that is 5.4 mm long and 2.6 mm wide? Round to

Vlad1618 [11]

Hey!

Area is equal to length × width. First find the area of the rectangle.

$5.4 \times 2.6 = 14.04$

The area of the rectangle is 14.04 mm². That means the area of the square is also 14.04 mm². In a square, all 4 sides are the same. The length and width are the same.

Try all choices and see which is the closest

$3.75 \times 3.75 = 14.06$

$3.87 \times 3.87 = 14.98$

$4.01 \times 4.01 = 16.08$

$4.32 \times 4.32 = 18.66$

The 1st choice is the closest.
