$\bf \textit{volum of a pyramid}\\\\ V=\cfrac{1}{3}Bh~~ \begin{cases} B=area~of\\ \qquad its~base\\ h=height\\[-0.5em] \hrulefill\\ B=\stackrel{18\times 18}{324}\\ h=12 \end{cases}\implies V=\cfrac{1}{3}(324)(12)\implies V=1296$

Alice is building a caterpillar habitat for some caterpillars she found in her back yard. She plans to cover all sides of the ha

fomenos

Answer:

3.04 m²

Step-by-step explanation:

Surface Area =0.8x0.4 = 0.32 (two of these - one on each end)

1x0.4=0.4 (two of these - top and bottom) (Strange to cover bottom with screen, but have to follow the directions.)

1x0.8=0.8 (two of these - front and back)

TOTAL = 0.32+0.32+0.4+0.4+0.8+0.8=3.04

2(4-16) - (-30)
= 2(-12) -(-30)
= 24 - (-30) ....Error right here....a negative multiplies a positive = negative (= -24 + 30)
= 24 + 30
= 54

Correct:
2(4-16) - (-30)
= 2(-12) -(-30)
= -24 - (-30)
= -24 + 30
= 6
