What is the surface area of this right prism?

Amiraneli [1.4K]

Answer:

Since the 'base' and 'top' of any prism have the same shape, the surface area can be found by

surface area of prism = 2 * area of base + perimeter of base * H

So for the rectangular prism in your example..

surface area = 2LW + 2(L+W)H

= 2 * 7 * 4 + 2*(7+4)*5

= 56 + 2 * 11 * 5

= 56 +110

= 166 sq cm

Hope this helps

Provide a counterexample:

Jobisdone [24]

Answer:

$a=2 \quad \text{and} \quad b=-2$

Step-by-step explanation:

Take $a=2 \quad \text{and} \quad b=-2$ , note that

$2=(-1)\cdot(-2)$

hence b divides a. On the other hand, we have that

$-2=(-1)\cdot2$

which tells us that a divides b. Moreover, $a=2 \neq -2=b$ .
