Step-by-step explanation:
Okkk so Surface area is the area of all the surfaces added together, this triangular prism consists of
2 triangles and 3 rectangles
To find the area of a triangle you do base x height divided by 2
To find the area of a rectangle
Length x width
Sooooo
Side 1= triangle
12x16/2: 96
Side 2= triangle
12x16/2: 96
Side 3= rectangle
12x10: 120
Side 4= rectangle
16x10: 160
Side 5= rectangle
10x20: 200
To find the SURFACE AREA
add them all together
96+96+120+160+200= 672 centimeters squared
Or square centimeters
SURFACE AREA UNITS is always squared so like square meters, centimeters, millimeters etc

8 x 5 x 5 = 200cm^3
8 x 8 x 1 = 64 cm^3
200 + 64 = 264cm^3
The answer would be 1.5 because you add .75 +.75 to get the answer
Answer is 9.5 First find DC by doing the Pythagorean theorem
BC is 3 BD is 5
So 3^2+ DC= 5^2
9+____=25
So DC is 4 cuz 4times 4=16
Now add AD+DC=AC
5+4=9
So BC is 3 the bottom AC is 9
3^2+9^2= 9+81=90 the sq rt of 90 is 9.5
Answer:
1/600 or 0.00166666 in decimal
Step-by-step explanation:
6*10^-2=1/(6*10^2)=1/(6*100)=1/600
