Answer:
<em><u>152.16</u></em>
Step-by-step explanation:
A=2(wl+hl+hw)
= 2 ( 2.3 * 5.6 + 8 * 5.6 + 8 * 2.3 )
= 2 ( 12.88 + 44.8 + 18.4 )
= 2 ( 76.08 )
= <u>152.16</u>
Answer:
152.16 yd²
Step-by-step explanation:
2(8 x 5.6) + 2(8 x 2.3) + (2.3 x 8) = 152.16 yd²

Answer:
The angles are called Vertical Angles. And vertical angles are always equal. So,
2x + 6 = 32
2x = 26
x = 13
Lateral surface area, is the area that is not including bases
so it is an area of free rectangles
3*(5*8)=3*40=120 cm²
Answer:
h = √91 cm
Step-by-step explanation:
Apply pythagorean theorem, a² + b² ° c².
Where,
a = ½(6) = 3 cm
b = h
c = 10 cm
Plug in the values
3² + h² = 10²
9 + h² = 100
9 + h² - 9 = 100 - 9
h² = 91
h = √91 cm
