The total surface area of the prism is 224 square units
<h3>Surface area of a rectangular prism</h3>
The formula for calculating the formula of a rectangular prism is expressed as:
TSA = 2(lw + wh +lh)
Given the following parameters
length = 8cm
Width = 8cm
Height = 3cm
Substitute
TSA = 2(8(8)+8(3)+8(3))
TSA= 2(64+48)
TSA = 224 square cm
Hence the total surface area of the prism is 224 square units

Domain of 8/(x - 6) = (-∞, 6) ∪ (6, ∞)
Answer:
x=3, y=0.8
Step-by-step explanation:
8x+5y=28
4x+5y=16
Subtract the second simultaneous equation from the first.
You are left with: 4x=12
12/4=3
x=3
Substitute this back into one of the equations.
8(3)+5y=28
8*3=24
28-24=4
4=5y
4/5=0.8
y=0.8
(Area of total floor) - (area of rug) = area of exposed wood.
(19ft x 15ft) - (pi r^2)=
(285) - [pi (4.5)^2]= 221.38 square feet
221.4 square feet
The angle between the two tangents drawn from an external point to a circle and the angle subtended by the line segment joining the points of the contact at the Centre are supplymentary,
So,
15.) let the unknown angle be x
=》x + 55° = 180°
=》x = 180° - 55°
=》
16. let the unknown angle be n
=》n + 80° = 180°
=》n = 180° - 80°
=》
