A rectangular prism is 7 cm long, 4 cm wide and 4 cm tall. How many 2 times 2 times 2 cm cubes can the prism be cut into? What i

Fantom [35]

Answer: The number of 2 times 2 times 2 cm cubes is 14. The total surface area of all the 2 times 2 times 2 times cm cubes is 336 cm square. The total volume of all the 2 times 2 times 2 times cm cubes is 112 cm cube.

Explanation:

It is given that the A rectangular prism is 7 cm long, 4 cm wide and 4 cm tall.

The volume of rectangular prism is,

$V_1=l\times b\times h$

$V_1=7\times 4\times 4$

$V_1=112$

Therefore, the volume of rectangular prism is 112 cm square.

The volume of cubes is,

$V_2=a^3$

$V_2=(2)^3$

$V_2=8$

The number of cubes in the rectangular prism is,

$N=\frac{V_1}{V_2} =\frac{112}{8} =14$

Therefore, the number of cubes is 14.

Total surface area of a cube is,

$A=6a^2$

$A=6(2)^2$

$A=24$

Total surface area of all cubes is,

$14\times A=14\times 24=336$

Therefore the total surface area of all cubes is 336 cm square.

Total volume of all cubes is equal t the volume of rectangular prism, i.e, 112 cm cube.

Write each number in standard form 62 hundreds and 30 tens

mestny [16]

We are given : 62 hundreds and 30 tens .

To find : the number in standard form.

Soltuion: We know hundreds represents times 100.

Also tens reprents times 10.

In order to find the values of 62 hundreds, we need to multiply 62 by 100.

In order to find the values of 32 tens, we need to multiply 32 by 10.

62 × 100 = 6200

32 × 10 = 320.

Now, we need to add those numbers above.

6200 + 320 = 6520.

In simple, we could also show as

62 hundreds and 30 tens = 62 × 100 = 30 × 10 = 6200+300 = 6520.

Therefore, standard form is 6520.
