Answer:

27 cm³

Step-by-step explanation:

The surface area of a cube is ...

SA = 6s²

Then the edge length is ...

54 cm² = 6s² . . . . . please note that cm³ is not the appropriate unit for area

9 cm² = s² . . . . . .divide by 6

3 cm = s . . . . . . . take the square root

The volume of a cube is ...

V = s³

V = (3 cm)³ = 27 cm³

The volume of the cube is 27 cm³.

a ladder 13m long is placed on the ground in such a way that it touches the top of a vertical wall 12m high. find the distance o

Sergio039 [100]

Answer:

by applying Pythagoras theorem;

the ladder(13m) acts as hypotenuse

the wall (12m) acts as height

the distance between the the two is the base

therefore

a² + b² = c²

b²= c²- a²

b²= 169 - 144

b² = 25

√b² = √25

b= 5m

the distance is 5m

Please help! use the net to find the lateral area of the prisim

Sergio039 [100]

Answer: 832 cm².

Step-by-step explanation:

1. To calculate the lateral area of the prism by using the net you must:

- Calculate the perimeter of the base:

$P=2l+2w$

Where l is the lenght and w is the width:

$l=17cm\\w=15cm$

Then:

$P=2(17cm)+2(15cm)=64cm$

- Now you must multiply the perimeter by the height. The height is 13 cm.

Then, the lateral surface area is:

$LA=64cm*13cm=832cm^{2}$
