Answer:

18

Step-by-step explanation:

I think the attached phôt below is your full question.

<u>And here is my answer: </u>

Surface area of a triangular prism = hight * area of the base

Here we have:

  • h= 12
  • Area of the base = 1/2 *2* 1.5 = 1.5

=> Surface area = 12*1.5 = 18

What is the difference of the volumes of the two oblique pyramids, both of which have square bases? Round the volumes to the nea
ad-work [718]

Answer:

Step-by-step explanation:

See attachment for the figure

Volume of pyramid can be defined as

V = 1/3 x area of the base x height.

-> Pyramid A:

Volume of Pyramid can be determined by:

V = 1/3 x (2.6cm)² x (2cm) = 4.5067 cm³

Pyramid B:

Volume of Pyramid can be determined by:

V = 1/3 x (2cm)² x (2.5cm) =  3.3333 cm³

Difference b/w two oblique pyramids: 4.5067 cm³ - 3.333 cm³ = 1.17 cm³

By Rounding the volumes to the nearest tenth of a centimeter

1.17cm³ ≈ 1.2cm³

Therefore,  the difference of the volumes of the two oblique pyramids is 1.2cm³
