17.	7.A cubical box with lid has a length of 30 cm. Find the cost of painting the insideand outside of the box at 5.50 per m².
Answer» ANSWER: PLEASE MARK MY ANSWER AS BRAINIEST Step-by-step explanation: Solution :- We have to find the surface area of the CUBICAL box. Surface area of the cube = 6a² where a = 30 cm ⇒ 63030 ⇒ 5400 sq cm As the cubical box has to be painted both from the outside and inside. So, the total surface area = INNER surface area + outer surface area ⇒ 5400 + 5400 = 10800 sq cm As we know that 1 sq m = 10000 sq cm Surface area in sq m = 10800/10000 Surface area in sq m = 1.08 sq m Cost of painting the cubical box = Rs. 5.50 per sq m Total cost of painting = 5.5*1.08 Total cost = Rs. 5.94 So, the total cost of painting the cubical box from outside and inside is Rs. 5.94

7.A cubical box with lid has a length of 30 cm. Find the cost of painting the insideand outside of the box at 5.50 per m².

Answer»

ANSWER:

PLEASE MARK MY ANSWER AS BRAINIEST

Step-by-step explanation:

Solution :-

We have to find the surface area of the CUBICAL box.

Surface area of the cube = 6a² where a = 30 cm

⇒ 6*30*30

⇒ 5400 sq cm

As the cubical box has to be painted both from the outside and inside.

So, the total surface area = INNER surface area + outer surface area

⇒ 5400 + 5400

= 10800 sq cm

As we know that 1 sq m = 10000 sq cm

Surface area in sq m = 10800/10000

Surface area in sq m = 1.08 sq m

Cost of painting the cubical box = Rs. 5.50 per sq m

Total cost of painting = 5.5*1.08

Total cost = Rs. 5.94

So, the total cost of painting the cubical box from outside and inside is Rs. 5.94

Ravi deposited * 12000 in a saving account whichgives 3% interest rate and 18000 to the accountwhich gives 5% interest rate. How much money willhe have after 6 years in both the accounts?

Answer»

Step-by-step EXPLANATION:

FIRST ACCOUNT

PRINCIPAL =₹12000

Rate =3%

time=6years

$interest \: = \frac{12000 \times 3 \times 6}{100}$

$= ₹2,160$

amount=₹12000+₹2160

=₹14160

second account

principal=₹18000

rate=5%

time=6years

$interest = \frac{18000 \times 5 \times 6}{100}$

$=₹5400$

amount=₹18000+₹5400

=₹23400

total money=₹23400+₹14160

=₹37,560
