Answer:

The answer to your question is 24 cm³

Step-by-step explanation:

Data

Initial volume = 2/5

Additional volume = 42 cm³

Final volume = 4/7

the total volume of the glass = ?

Process

1.- Write a proportion to help you solve the problem

42 cm³ -------------------- 4/7 of the total

x ------------------- 7/7

2.- Solve the proportion

x = (7/7 x 42) / 4/7

3.- Simplification

x = 42 / 4/7

x = 168/7

x = 24 cm³

Mamont248 [21]

Answer:

Area of the square pyramid = $156\,cm^2$

Step-by-step explanation:

The Surface area of the square pyramid :

Area of the four triangular faces+ Area of the square base

$=(2\times Base \times Height )+ (Side\times Side)$

For triangle:

$Base=6\,cm\\Height=10\,cm$

Side of the square base= $6\,cm$

Area of the figure is:

$=(2\times 6 \times10 )+(6\times 6)\\\\=120+36\\\\=156\,cm^2$

The area of the square pyramid is : $156\,cm^2$

Find the value of x. If your answer is not an integer express it in simplest radical form.

statuscvo [17]

Answer:

Step-by-step explanation:

To find the value of x, using Pythagorean theorem.

7) x² = 12² + 12²

= 144 + 144

= 288

x = √2*12*12

x = 12√2

8) x² + 9² = 18²

x² + 81 = 324

x² = 324 - 81

x² = 243

x = √3*9*9

x = 9√3
