Nikitich [7]

Answer:

24 m³

Step-by-step explanation:

We need to find the volume of the prism. Given that , rectangular prism with cubic units arranged in two rows of two with six total layers . And the volume of each unit is 1 m³ .

<u>Volume</u><u> of</u><u> </u><u>one</u><u> </u><u>unit </u><u>:</u><u>-</u><u> </u>

\rm\implies Volume_{one\ unit } = 1m^3

<u>By </u><u>Unitary</u><u> Method</u><u> </u><u>:</u><u>-</u><u> </u>

Volume of two cubes , will be :-

\rm\implies Volume_{two\ unit } = 2m^3

<u>Volume</u><u> of</u><u> </u><u>one </u><u>layer </u><u>:</u><u>-</u><u> </u>

\rm\implies Volume_{one\ layer } = 4m^3

<u>Volume</u><u> of</u><u> </u><u>six </u><u>layers </u><u>:</u><u>-</u><u> </u>

\rm\implies Volume_{6\ layers } = 4m^3\times 6 \\\\\rm\implies \boxed{\rm Volume_{6\ layers } = 24 \ m^3}

5x - 47&lt; 3(12x - 108) – 2​
TEA [102]

Answer:

9 < x

Step-by-step explanation:

5x - 47< 3(12x - 108) – 2​

Distribute

5x - 47< 36x - 324 – 2​

Combine like terms

5x - 47< 36x-326

Subtract 5x from each side

5x-5x - 47< 36x-5x-326

- 47< 31x-326

Add 326 to each side

326 - 47< 31x-326+326

279 < 31x

Divide by 31 on each side

279/31 < 31x/31

9 < x
