Answer:

$\boxed{\textsf{ The total surface area of the cuboid is \textbf{62 cm} $\sf ^2$ .}}$

Step-by-step explanation:

Given that the base area of the cuboid is 7cm² . And it's volume is 21cm³ . We need to find its total surface area . Now here we need to find the height . We can find height as ,

Height :-

$\qquad\boxed{\boxed{\sf Height =\dfrac{ Volume}{Area } }}$

$\sf\implies Height =\dfrac{Volume}{Area} \\\\\sf\implies h =\dfrac{ 21cm^3}{7cm^2}\\\\\implies \boxed{ \pink{\frak { Height = 3 cm.}}}$

$\rule{200}2$

Let's find out the Total surface area .

TSA of cuboid :-

$\qquad\boxed{\boxed{\sf TSA_{(cuboid)} =2(lb + bh + hl ) }}$

Put on the respective values :-

$\sf\implies TSA_{(cuboid)}= 2( lb + bh + hl )\\\\\sf\implies TSA_{(cuboid)}= 2( 7cm\times 1cm + 1cm\times 3cm + 3cm \times 7 cm ) \\\\\sf\implies TSA_{(cuboid)}=2 ( 7cm ^2+3cm^2+21cm^2 ) \\\\\sf\implies TSA_{(cuboid)}= 2\times 31cm^2 \\\\\sf\implies \boxed{\pink{\frak{ TSA_{(cuboid)}= 62 cm^2}}}$

The function f(x) = 3,005(1 + 0.03)x represents the amount of money in a savings account where x represents time in years. What

Damm [24]

Answer:

Principal or Initial Amount of Money

Step-by-step explanation:

Given, f(x) = 3005(1+0.03)^x.

Now, comparing with f(x)= ab^x where

a = initial value

b = rate of growth

x = time or period

This, function is an exponential growth function. So by comparing we get a= 3005 which is the initial value b = 0.03.

But in this case according to the question, the function f(x)= 3005(1+0.03)^x represents the amount of money in a savings. So the answer is 3005 which is the initial money.

Lulu found a recipe for her favourite snack: yogurt covered peanut clusters. Lulu wanted to make a large batch of peanut cluster

antoniya [11.8K]

Answer:

How much would it cost to buy 10 pounds of peanuts?

Answer: $35

What is the cost per pound?

Answer: $3.50

Step-by-step explanation:

So first, to find the anser to the first question, we need to find out the second question. So, what is the cost per pound.

Well if she got 4 pounds for $14, we should try dividing 14 by 4.

14 divided by 4 = 3.5 ($3.50)

So the cost per pound is $3.50

Now to find out how much it costs if Lulu bought 10 pounds, we need to multiply.

10 x 3.5 = 35

So if she bought 10 pounds, she would play $35
