Cross Sections of Geometric Solids Question 1 of 5
XA
Kevin cuts a foam block along the red line. When he looks at the newly
exposed face, what is the shape of the cross-section?
4 cm
7 cm
5 cm
O A. A rectangle, 5 cm by 7 cm
O B. A rectangle, 4 cm by 5 cm
OC. A square, 4 cm by 4 cm
O D. A rectangle, 4 cm by 7 cm

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
