Answer:
Surface area of 5 sides = 51.2 cm²
Step-by-step explanation:
Given:
Side of cube = 3.2 cm
Find:
Surface area of 5 sides
Computation:
Surface area of 5 sides = Surface area of cube - Surface area 1 side
Surface area of 5 sides = 6a² - a²
Surface area of 5 sides = 6(3.2)² - (3.2)²
Surface area of 5 sides = 6(10.24) - 10.24
Surface area of 5 sides = 6a² - a²
Surface area of 5 sides = 61.44 - 10.24
Surface area of 5 sides = 51.2 cm²
Answer:
1/12 foot
Step-by-step explanation:
M∠2 = 180 - m∠1 = 180 - 3x [supplementary angles<span>]
</span>In a triangle, the three interior angles always add to 180° ⇒
m∠2 + m∠3 + m∠5 = 180 <span>
180-3x + 2x+20 + 30 = 180
230 - x = 180
x = 230 - 180
x = 50</span>
