Answer:
Given
Edge of a cube = 10cm
Length, l = 12.5 cm
Breadth, b = 10cm
Height, h = 8 cm
Find out
We have to find
i) Which box has the greater lateral surface area and by how much?
ii) Which box has the smaller total surface area and by how much?
Solution
(i)
Lateral surface area of a cube = 4 * (edge)2
= 4 * 102 cm2
= 400 cm2
Lateral surface area of a cuboid = 2 (lh + bh)
= 2 (12.5 * 8 + 10 * 8) cm2
= 2 (100 + 80) cm2
= 360 cm2
So, the lateral surface area of the cubical box is greater than cuboidal box by (400 cm2 – 360 cm2) which is 40 cm2.
(ii)
Total surface area of a cube = 6 * (edge)2
= 6 * 102 cm2
= 600 cm2
Total surface area of cuboid = 2 (lb + bh + lh)
= 2 (12.5 * 10 + 10 * 8 + 12.5 * 8) cm2
= 2 (125 + 80 + 100) cm2
= 610 cm2
Therefore, the total surface area of the cuboidal box is greater than the cubical box by (610 cm2 – 600 cm2) which is 10 cm2.
divide total miles driven by time:
105 miles / 2.5 hours = 42 miles per hour
Answer:
4t
Step-by-step explanation:
Let's form an equation here just to put it visually.
So it would be t+3*t
We can also write this as t+3t (If they're right next to eachother, it still indicates multiplication)
Now we can do t+3t which is 4t
If this doesn't make sense, then you can look at it this way
You do 1t+3t and since they're like terms, you can combine them and do 4t.
Multiply 35 by 97 to figure out how many strawberries there were: 35•97=3,395. Divide by 14 to figure out how many punnets: 3395/14=242.5. Multiply by 1.95 to figure out how much the strawberries went for: 242.5•1.95=472.875. Round to the nearest cent: 472.875=472.88. The answer: $472.88 :)
