Answer:
<h2>64 cm²</h2><h2 />
Step-by-step explanation:
surface area of a square base pyramid = base area + 4 ( triangular sides area)
where:
base = 4 cm
side height length = 6 cm
Surface area = 4² + 2(4)6
= 16+ 48
= 64 cm²
First we need to know how much each pen costs. So we take 11.77 and divide it by 11. That gives us 1.07 per pen. So answer choice A has 4 pens for 4.44, so we need to multiply 1.07 x 4. That gives you 4.28, so we know that isn't the correct answer. For option B, we need to multiply 1.07 x 5. That is 5.35, so that also can't be the answer. For C, we need to do 1.07 x 6, and that gives us 6.42. So we know the correct answer is option C.
