Lateral surface area of the prism = 920 in²

Total surface area of the prism = 1180 in²

Solution:

Length of the prism = 13 in

Width of the prism = 10 in

Height of the prism = 20 in

Lateral surface area of the prism = 2(l + w)h

= 2(13 + 10) × 20

= 2(23) × 20

= 920 in²

Lateral surface area of the prism = 920 in²

Total surface area of the prism = Lateral area + 2lw

= 920 + 2 × 13 × 10

= 920 + 260

Total surface area of the prism = 1180 in²

Hence Lateral surface area of the prism = 920 in²

Total surface area of the prism = 1180 in²

Step-by-step explanation:

<h3><u>★ Solution :-</u></h3>

$\sf \longmapsto 98^2$

$\sf \longmapsto (a - b)^2 = a^2 - 2ab + b^2$

Here,

a = 100
b = 2

$\sf \longmapsto (100 - 2)^2 = 100^2 - 2(100)(2) + 2^2$

$\sf \longmapsto 100^2 - 2(100)(2) + 2^2$

$\sf \longmapsto 10000 - 400 + 4$

$\sf \longmapsto 9606$
