Can someone help? I know the volume can someone help with the surface area?
TEA [102]
To find the surface area you will find the area of each flat surface or each face.


The faces are in the shape of a rectangle , so multiply the length by the width.

A = lw
Front/ Back-3 1/2 x 3 1/3 = 11 2/3 ft.²

Sides- 3 1/3 x 3 1/3 = 11 1/9 ft.²

Top/bottom - 3 1/2 x 3 1/3= 11 2/3 ft.²

Add together to get the total surface area.

11 1/9+11 1/9+11 2/3+11 2/3+11 2/3+11 2/3 = 68 8/9 ft.²

The total surface area is 68 8/9 ft.².

0²=0

1²=1

2²=4

3²=9

4²=16

5²=25

6²=36

8²=64

9²=81

10²=100

Now,

According to your question,

  1. The two numbers should be square numbers
  2. They should be greater than 1.
  3. Their sum should be 100.

Hence, your given conditions matches with the numbers 64 and 36.

Therefore, the numbers are 64 and 36.

Softa [21]

Answer:

PN= $17,800

Step-by-step explanation:

<u>La formula general para calcular el activo de una empresa es la siguiente:</u>

<u></u>

A= PN + P

El activo es igual al patrimonio neto y el pasivo.

Debemos intercambiar los términos:

PN= A - P

Activo:

Caja= 10,000

Bancos= 13,500

Equipos de computación= 2,400

Documentos por cobrar= 5,100

Pasivo:

Cuentas por pagar= 8,000

Documentos por pagar= 4,000

Intereses por pagar= 1,200

PN= 31,000 - 13,200

PN= $17,800
