Ann [662]

<span>This is a tricky question that Reina and Sam are multiplying (84)5 (73)9
and their work are
</span><span>(84)5 (73)9 = 84 + 573 + 9 = 89712 Reina's
(84)5 (73)9 = 84⋅573⋅9 = 820727 Sam's
Actually they are doing or multiplying using exponents.

</span>

Reina’s work (8⁴)₅(7³)⁹=8⁴⁺⁵+ 7³⁺⁹= 8⁹ 7¹²<span>
This is incorrect because she added exponents instead of multiplying exponents

Sams work (8</span>⁴<span>)</span>⁵<span> (7</span>³<span>)</span>⁹<span>=8</span>⁴ˣ⁵<span> 7</span>³ˣ⁹<span>= 8</span>²⁰<span> 7</span>²⁷<span>
<span>This is correct because Sam multiplied exponents correctly</span></span>

The diagram shows the net of a juice box. The box is a rectangular prism.

Hoochie [10]

Answer:

269.6 square centimeters

Step-by-step explanation:

<u><em>The correct question is</em></u>

The diagram shows the net of a juice box. the box is a rectangular prism. what is the surface area of the juice box? 6.4 cm 4 cm 10.5 cm

we know that

The surface area of a rectangular prism is equal to

$SA=2B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

we have

$L=6.4\ cm\\W=4\ cm\\H=10.5\ cm$

<em>Find the area of the base B</em>

$B=LW$

substitute the given values

$B=(6.4)(4)=25.6\ cm^2$

<em>Find the perimeter of the base P</em>

$P=2(L+W)$

substitute the given values

$P=2(6.4+4)=20.8\ cm$

<em>Find the surface area</em>

$SA=2B+PH$

substitute

$SA=2(25.6)+(20.8)10.5=269.6\ cm^2$
