When making a book cover, Anwar adds an additional 20 square inches to the surface area to allow for overlap. How many square in

e-lub [12.9K]

Answer:

234 square inches

Step-by-step explanation:

We are given that

Length of book, l=11 in

Width of book, w=8 in

Height of book, h=1in

Additional area required to overlap=20 square inches

We have to find how many square inches of paper to make cover of one book.

We know that surface area of cuboid

$S=2(lb+bh+hl)$

Using the formula

Surface area of book

$S=2(11\times 8+8\times 1+1\times 11)$

$S=214 in^2$

Total paper used to make cover of one book

=Surface area of book +additional surface area

= $214+20$

$=234in^2$

Hence, Anwar will use paper to make cover of one book=234 square inches

Find the value of Y! please help

Maurinko [17]

Answer:

y = 5.6

Step-by-step explanation:

Use Sine

Sine = $\frac{opposite}{hypothenuse}$

Sine 45 = $\frac{y}{18}$

Sine of 18 is 0.309

0.309 = $\frac{y}{18}$

Multiply 18 on both sides

0.309 x 18 = $\frac{y}{18}$ x 18

5.562 = y

Round to the nearest tenth:

5.562 = 5.6
