Step-by-step explanation:
To find the total surface area of a prism, you need to calculate the area of two polygonal bases, i.e., the top face and bottom face. And then calculate the area of lateral faces connecting the bases. Add up the area of the two bases and the area of the lateral faces to get the total surface area of a prism.
Hope this helps!
All the love, Ya boi Fraser :)
Step-by-step explanation:
given,
the complete angle is complementry angle which is 90°
let the first angle be x and second angle be 7x ( as second angle is 7 times more than first angle )
now,
→ x + 7x = 90
→ 8x = 90
→ x = 90/8 = 11.25
therefore
1st angle = x = 11.25°
2nd angle = 7x = 7 × 11.25 = 78.75°
hope this answer helps you dear take care and may u have a great day ahead!
Answer:
given :
24 hours = 1 day
now
60 hours = 60 / 24 = 2.5 days
Answer:
Option A and E.
Step-by-step explanation:
It is mentioned that Chiyo has a toolbox having a rectangular prism shape with a length of 8 inches, width of 15 inches, and height of 6 inches.
In addition to this, A triangular prism with a triangular base with base 8 inches and height 3 inches. The prism has a height of 15 inches.
So here the shape can be broken into a triangular prism and rectangular prism
Therefore the first option is correct
Now as we know that
Volume of the rectangular prism is
= l×b× h
= 8 × 15 × 6
= 720
And, the volume of the triangular prism is bh
And, the area of the triangular prism is 1 ÷ 2 × b × h
= 1 ÷ 2 × 8 × 3
= 12
Now the volume is
= 12 × 15
= 180
So, the volume of the tool box is
= 720 + 180
= 900
Hence, the last option is correct
The answer is multiplication
