Answer:
Total surface area of the rectangular prism is 150.88 cm^2
Step-by-step explanation:
area of base = area of top
area of base = 5 x 3.1 = 15.5 cm^2
Area of small lateral surface having dimensions 3.1 cm x 7.4 cm is
=3.1 x 7.4 = 22.94 cm^2
Area of big lateral surface having dimensions 5 cm x 7.4 cm is
=5 x 7.4 = 37 cm^2
Total area of prism = 2 x 15.5 + 2 x 22.94 + 2 x 37 = 150.88 cm^2
total surface area of the rectangular prism is 150.88 cm^2
The minimum number of times would be 5 times.
There are several important information's already given in the question. Based on those given information's the answer can be easily deduced.
Ratio of the radii of two spheres = 9 : 2
then
Ratio of the volume of the two spheres = 9^3 : 2^3
= 729 : 8
I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
I'm sure that the hypotenuse is 13 yards
Here's the formula used:
Length of Hypotenuse² = Length of side 1² + Length of side 2²
So here's how to solve this question:
12 squared + 5 squared = hypotenuse
(Then square the values)
144 + 25 = 169
Divide 169 by the square root to get the length of the hypotenuse: 13
Hope this helps!
