Answer:
300 in.³
Step-by-step explanation:
We find the volume of 1 prism and multiply it by 2.
V = BH
where V = volume of prism, B = area of the base of the prism, H = height of the prism
V = ½bh × H
V = ½(5 in.)(6 in.) × 10 in.
V = 150 in.³
That is the volume of one triangular prism. Now we multiply it by 2.
volume = 2 × 150 in.³ = 300 in.³
Answer:
20 m by 10 m
Step-by-step explanation:
let w be width and l be length , then
2(l + w) = 60 ( divide both sides by 2 )
l + w = 30 ( subtract w from both sides )
l = 30 - w → (1)
lw = 200 → (2)
Substitute l = 30 - w into (2)
w(30 - w) = 200 ← distribute parenthesis on left side
30w - w² = 200 ( subtract 200 from both sides )
30w - w² - 200 = 0 ( multiply through by - 1 )
w² - 30w + 200 = 0 ← in standard form
(w - 10)(w - 20) = 0 ← in factored form
Equate each factor to zero and solve for w
w - 10 = 0 ⇒ w = 10
w - 20 = 0 ⇒ w = 20
Substitute these values into (1)
l = 30 - 10 = 20
l = 30 - 20 = 10
dimensions of field is 20 m by 10 m
