Answer:
Density of steel = 80.73 gm/
Step-by-step explanation:
The figure is made up of cuboid and square pyramid.
Height of cuboid, h = 9 cm
Length of cuboid, l = 6 cm
Width of cuboid, w = 6 cm
Volume of cuboid is given by the formula:
Density of Wood , = 0.68g/
We know that formula of Density is:
Putting the values:
Total weight =
970 = 220.32
= 749.68 gm
Volume of pyramid is given as:
Base is a square with side 6 cm
Density of Steel/Pyramid:
The expression of sinU as a fraction is 12/13
Find the diagram attached.
To get the fraction represented by sinU, we will use the SOH CA TOA identity.
From the diagram;
- Hypotenuse = SU = 13
- Opposite = ST = 12 (angle opposite to m<U)
Since sin theta = opp/hyp
SinU = ST/SU
SinU = 12/13
Hence the expression of sinU as a fraction is 12/13
