The present shown below is a cube. Find the surface area of the present. \text{ cm}^2 cm 2

2400 cm^2

Step-by-step explanation:

The surface area of one side of this 6-sided figure is (20 cm)^2, or

400 cm^2.  Multiplying this result by 6, we get the total surface area:

6(400 cm^2) = 2400 cm^2

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
