Given:
A figure of a rectangular prism with length l, width w and height h.
To find:
The surface area of the rectangular prism.
Solution:
The product of twice of the length l and the width w is:
...(i)
The product of twice of the length l and the height is:
...(ii)
The product of twice of the width w and the height h is:
...(iii)
The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:


Therefore, the required expression is
.

Answer:
B. 54
Explanation:
Take 72 from 180.
180 - 72 = 108.
Since there are two y's AND they're congruent, divide 108 by two and get 54.
Ummm I'm not sure but let me do the math and I'll tell u :)
Answer:
Area of the base is 10.5 cm².
Step-by-step explanation:
Formula for the volume of the given oblique prism = Area of the triangular base × Vertical height between two triangular bases
Vertical height = 6 cm
Volume = 63 cm³
From the formula,
63 = Area of the triangular base × 6
Area of the base = 
= 10.5 cm²
Therefore, area of the base is 10.5 cm².
