Answer: 1+1-1+2+3/4x8+56+1-7 = 59
Let's find the area of the base.
It's a rectangle that's 3.8 by 4.8, so let's multiply.
3.8×4.8=18.24
We have two different triangles.
Triangle one has a height of 2.6 and base of 4.8. But there are two of them.
2.6×4.8×0.5=6.24×2= 12.48; this is the area of two triangles.
Another set of triangles has a height of 2.9 and a base of 3.8.
2.9×3.8×0.5=5.51×2=11.02
Let's add all the areas together.
18.24+12.48+11.02
41.74
The surface area is 41.74 m², so the third option.
To solve this problem all you need to do is multiply how many gallons of water Lena put in the bucket(4.5 gallons) times how much one gallon of water weighs(8.35 pounds).
(4.5)(8.35)=37.58 lbs
Answer:
The dimensions of AEHD are 3 inches and 3 inches
The perimeter of AEHD = 4 × 3 = 12 inches
Step-by-step explanation:
* The figure is a rectangular prism
- It has two rectangular bases DCGH and ABFE with dimensions
4 inches and 3 inches
∵ DC = 4 inches and CG = 3 inches
∴ HG = 4 inches and DH = 3 inches
- It has two rectangular side faces ABCD and EFGH with
dimensions 4 inches and 3 inches
∵ DC = 4 inches and FG = 3 inches
∴ AB = EF = 4 inches and AD = EH = 3 inches
- It has two square side faces BCGF and ADHE with equal
dimensions 3 inches
∵ CG = 3 inches and FG = EH = 3 inches
∴ BC = 3 inches and BF = AE = 3 inches
∴ The dimensions of AEHD are 3 inches and 3 inches
∴ Its perimeter = 4 × 3 = 12 inches
A decagon has 10 sides therefore it has 10 interior angles
